got some color on it
« on: May 15, 2008, 03:27:36 PM »
Here you are a couple of months into a project, or in my case a couple of years, and it is finally time to start painting. You have this great paint scheme in your head, 7 colors and letters everywhere, and you are about to embark on an endless sea of tape and masking paper. All of a sudden your tricked out 7 color scheme goes down to 2 colors and some clear and you get your plane done and in the air. Later after the fact you always look it over and think "I wish I had gone that little extra step." The above scenario has happened to me many times in the past. Luckily Bill Wilson and Brad Walker turned me onto a very quick way of painting a plane, FORWARD MASKING.

We have all heard of back masking. You apply tape and masking paper all over the plane then paint on a color. Then remove all the tap and masking paper and then tape and over the color you just painted and paint the next color. Then repeat continuously until you applied all your colors. This takes hours upon hours of work that can easily be avoided by forward masking your model as you paint.

First off you need to purchase a Hand-Masker made by 3M and sold at Home Depot. It applies masking tape to brown paper as you pull the paper off a roll. It is one of those tools you buy once and then wonder how you ever made it without one. It is awesome and real time saver. Plus it is designed with any masking job in mind. Painting a car, your house, or staining cabinets. If you need to mask off something this tool will be in your hand.

I need to tell you that I use base coat clear coat automotive paint exclusively. It is easy to work with and can be used in just about any weather condition and its bullet proof when it comes to sun exposure water exposure and yes raw fuel exposure. Granted you don't want to soak your plane in it but it can withstand fuel very well.

Now let's get started. You have a paint scheme in mind, think of the trim colors first. These will be applied first instead of last. You will be working backwards from how you probably have always done it, unless of course you already know how to forward mask. On my most recent model it was red white and blue with silver as the separating color or trim color. I have the plane sitting there in primer. I fill the gun with some silver and paint in the areas I know where the silver lines will be. Then I take 3M 1/4" blue tape and lay down the pattern I want to show, or be the final trim lines on the plane.

Next, I pick up the white. I know the top half of the fuse is white. I paint on some white all over the top half of the fuse. Yes, there is white getting on the rest of the fuse but it is really not that much to worry about. Let that white flash off for about 20-30 minutes and grab the hand masker and cover all the white area of the plane up to the tape that I laid down to leave a silver trim line.

Then I put some red in the gun and shoot red all along the center of the fuse and the cowl. Yes a little bit of red is on the lower fuse but as I said before it is minimal. Let this flash off as well. Then grab the hand masker and cover all the red area to the next tape line that hides the silver trim color. I left the white area covered up as well and just let the next mask cover it up as well.

Now I load the gun with blue. Paint the wing, flaps, elevators, and lower fuse. This takes a while due to the large area being painted. Once it is flashed off I grab my stencils I had cut at Penn Industries in Dallas. I pull the backing and place them in their designated areas. Grab the hand masker go all the way around each of the stencils to cover up the blue which is the rest of the plane. You can see from the photos it is just a big paper and tape blob on the paint stand. Put white in the gun and paint the stencils. This takes a few coats going over dark blue but it covers.

Now the fun begins. Start removing tape and paper and stencils. If the stencils and or tape seem to be stuck to the plane use a hair dryer to heat them up and it helps to release the adhesive. I do this when pulling any tape or stencil from my planes. Just very quickly pass over it with the dryer. Just enough to give it a little heat. I saw Windy doing that on a video and I have done it ever since and I have minimal troubles with peeled paint. That is another priceless tip you learn along the way. Remove the tape and paper in reverse order of how it was applied.

Stand back and admire your creation.

In the photos you see here I have about 9 hours in it from primer to where it stands right now. That means from the moment I turn on the shop light to the minute I turn it off, clean up and every thing. I have to work around children's nap times and they usually give me a three hour window during the day time. I started on a Friday night at 9pm worked until 12am. Then Saturday from 12pm to 3pm and Sunday from 12pm to 3pm. You can see from the photos it is a fairly simple paint scheme so it shouldn't take very long. But if I had wanted to add colors to the wing and tail it would have only taken a few extra properly placed pieces of tape and I would have had multiple colors all over the wing as well. I personally think simplicity with good color choices makes for a very attractive paint scheme. I can take no credit for this scheme as I ripped it right off the real Furias Reno air racer.

I still need to do some checker boards on the nose and paint the canopy. I had a senior moment and forgot to paint the canopy. I usually don't paint them so that is why I missed it. I should have painted first before the trim lines. Then I would have covered it and then painted with the silver and so on. Now I have to go back and mask around it and cover the plane and so on. I also have to add clear.

I would say I probably have another 3 to 4 hours to go and it will be in clear. I think it isn't that bad when full blown paint job can be had in just a few short sessions.

This process is insanely simple and the amount of time it saves is priceless in my book.

I cant thank Brad and Bill enough for teaching me this simple method. I hope it helps you as well.

NICE!

Sounds like you got there pretty quickly too.  Gonna factor this in the next paint job I do...

I use Omni brand paints.  I buy them at English color.  They are a PPG dealer.  It is a PPG off brand.  Pretty fair prices.  Like a pint of red that I used was $26 and I used one oz of it. That pint is mixed 1:1 with a reducer so you actually get a quart of color to work with when using it.  It will go along way on many planes.  It has a shelf life of 4-6 years.  I have even used a color that was 8 years old.  Had to shake it for quite while but it worked.  I think 6 is about the max I would push it though in the future.

Thanks for all the kind words.

Since the photos I have added the checkers on the nose.  But Hockey playoffs are now consumig some of my evenings and slowing the process a little.  Hope to get it in clear this weekend.

Hey Doug:
Thanks for the great how to.
What kind of clear coat will you be using?

You mentioned "can be sprayed in any weather".   Base coat, clear coat does not blush like dope does??

Doug,

Great post!

My only fear is that the tape used with the masker would be too high tack. It sounds like the heat gun answers that problem, provided no glue residue is left. If there is residue I don't know how you remove it before clearcoat, since the base coat colors will wipe off easily before the protective clear.

I love the basecoat/clearcoat system,since as you have said, weather / humidity is no longer a big problem, and it is soooooo much faster. One coat of each color usually does it.

Keep up the good work.

Tom,

I used to think the same thing about the masking tape 9it still scares me to death).  But the green masking tape from 3M is low enough tack to work as long as it is new or fairly new.  If the tape has been sitting around along time, years, it can get very gooey and then it is just a big blob of green goo!  Also at Home Depot there is a masking tape by 3M and it is Blue and it is usually lower tack then the green.  Also when you pull the paper and off the tape machine you can then stick it to your shirt once.  Then apply it to the plane along the tape line already on the plane.  If you are using the masking tape as the edge you are painting against dont do that as there will be little timy fuzzies from your shirt.  That really cuts the tackyness down when you do that.  But make sure you dont have wet paint on your shirt then stick it to your plane.  Ask me how I know that??!?!?!?!?!

When I remove tape I lay the tape line that I am pull back and pull it back at a sharp angle.  I dont just pull it up 90 degrees to the surface.  I have found through my experience it helps cut down on pull ups.  Maybe it is just in my head but since I started doing it that way it is much better.  The tape also pulls up cleanly along the color line giving it a very nice edge.

I've painted several planes with the basecoat/clearcoat urethane system. Works pretty well if you are able to use substate that doesn't cause problems. Ideally, having no open bays would be the best. Then you can use urethane on the bare wood up. That tends to work really well. Problem comes if you have to use dope for shrinking covering over open bays. But it's not an issue in an all sheeting airframe. I like the urethane basecoat stuff. It's extremely light and covers very well. As noted, it's one coat and you're done.

I plan on another plane using Auto Air Colors. Same thing; coverage in one, thin coat. Nice stuff.

Randy,

I use Sig nitrate dope for the substrate and have for years.  Then Nitrate and zinc for some fill.  Then clean it real good to get the dust off.  Then go to autoprimer, a thin guide caot a couple of times.  Then the paint is going over autoprimer.  That works really good for me over the last several years.

Doug,

Yep, that will work. Last plane I used urethane on, I did butyrate base, silkspan and veil, 3 or 4 coats of unthinned non-taunting butyrate, sand and shoot with K-36 catalyzed auto primer. Sand then a seal coat of heavily reduced clear urethane (not catalyzed), blocking coat of basecoat and on to colors with catalyzed urethane as a top coat. Worked pretty well. Big thing was to insure that the lacquer substrate had gased off sufficiently before shooting the auto primer and to be careful pulling up tape (the seal coat helps to lock down the primer to the substrate pretty well).

I do like the insensitivity of urethane to humidity and mostly to temp. It's nice to just shoot when you want to and not worry too much about conditions. Only real concern was getting the topcoat mix right for the temp (so it would flow and not orange peel on you). But other than that, it's pretty bulletproof.

One comment about "forward maskig" that is pertinent to using urethane. Urethane basecoat is light. It is mostly toners with a very mild binder so it doesn't weigh much. It allows doing paint schemes that may build up several layers of paint and you don't have to be overly concerned as you might with paints that may transfer more weight. The advantage of backmasking is, if done right, you end up with one layer of paint (color) on the plane. From a weight standpoint, this is great. But it's a pain the backside and just time consuming as heck (thus the 8 hour masking sessions). In a setup as Doug describes, you save yourself great gobs of time and it's just easier. The down side is, you may end up with several layers of paint on the plane. With a dope finish, this can be bad. But Doug notes, with urethane basecoat you use less paint due to it's incredible ability to cover with just a very thin coat and moreover, it's inherently lighter since it doesn't carry much binder (which also makes it hard to clear adhesive from, but that's another story). So overcoating with several layers isn't nearly as much of a concern, if any at all (as long as you don't get too carried away).

As a consequence to that, you can do pretty complicated paint schemes, not worry too much about overcoating and still end up with a reasonably light finish. To say nothing of the monster amounts of time saved since you didn't have to backmask.

You go Doug. This is me in the bleacher cheering you on!!   H^^

Got about another 1.5 hours on it. Checkers done and canopy is painted. You cant see it in the pics but I painted the canopy black then I put silver in the gun and closed it all the way and then open 1/16 of a turn and sprayed from 2' away. Then I did it with a metallic blue I have. Should jump in the sun but not over done. Black is still the main color of the canopy.

Oh yeah note to self: DON'T BE A DUMB A$$! Follow your own advice! I didn't heat the tape when pulling around the canopy and got some pulls along the fillet. Pissed me off real good. Already touched up and shouldn't be too noticeable. I taped it two days ago but didnt have time to get it painted so it sat stuck to the plane and I got all happy and ready to see it and skipped that very important step. Oh well, you would think I would live and learn, sometimes I just live instead.

Just needs some little touchups and a real good cleaning and it should be ready to go to clear! YIKES!! That is the scary part!
