What are you guys that build electrics using for paint?
Thanks
Mike

Automotive acrylic over dope for pretty models, or household acrylic on S#!tters

Good question and topic Mike. I'm lookin for something better than dope also. Acrylic may be a solution. :)

Hi Dan
The reason I ask the question is that I personally do not like using dopes and thinners to finish a model for various reasons. Furthermore, when fuelproofing is not a concern I do not see the necessity of using finishing materials to make it so. I have never tried to make the finish on a model a piece of art anyway but do want it to look nice. Any methods used in lieu of dope I would be interested in.
Thanks for the input

Ty have you ever used these and if so, how does it finish out?
Thanks

Rustoleum paints. ???

Duplicolor has a zillion different colors and if you are good with a buzzbomb you can get a decent finish without too much trouble.A little elbow grease and some "Death paint" makes it that much nicer.Trax

Acrylics/water colors. D>K From a tube. H^^
Mike,
I used them for years and still do as a gallery artist. I've even thinned them out for airbrush use, they cover nicely.
Downside is the cost and unless sprayed they won't brush out all that well.
With no fuel in the loop, I would imagine you could use normal but good quality aerosol can paint. Use clear when you're done with the colors.

Pittsbergh paints latex in sample sizes from Menard's. Mix 50/50 with water and either spray on or use a foam brush. It leaves a very light finish and you can get any color you want mixed.

Just because it doesn't have to be fuel resistant doesn't mean it doesn't have to resist other things. You want a finish that will withstand regular handling, possible water (rain) and general light abuse that our planes receive. You can use water based paints with a urethane topcoat or some such that will be durable. Painting it with watercolors may present a problem.

If you're going to fly in contests you're going to be in the pits right next to a lot of slime powered planes, shaking hands with slime pilots, etc.
If your paint can't stand being squirted with raw fuel by someone who's about to say "oops" and look real apologetic, then you may want to re-think your paint choice.

I've been using Duplicolor Paint Shop clear for the base and color. They come in quart cans. Top clear coat is Duplicolor rattle can acrylic lacquer because it is more fuel resistant than the Paint Shop clear. This helps protect the finish when helpers that fly nitro handle the plane. You can rub out the top coat for a very nice finish.

Thanks for all the suggestions guys. I think I have decided on what I am going to use. I do not fly in contests anymore and when I do fly, it is with freinds who belong to our club.

I'm considering using water based resin for a finish. Some tests I ran seem to indicate that it is very light and pretty hard. We'll see when the time comes.

Let me know how it turns out Randy
Thanks

I like acrylic lacquer, but it's getting harder to find. I had to scrounge toners from paint stores all over town for my last dog. Tim has a good point about other folks spraying or dripping. I tooted my acrylic-painted electric dog with IDP clearcoat to reduce the worry.

Monokote and SIG Dope.

I jusst read in the latest FM mag where some one is using Tamiya spray paints to redo electric RC models. Worth a read. H^^
My VECTRA was painted with a lot of different colors of Lexan car paint, the paints for plastic cars, I mixed it with DuPont thinner and SIG dope thinner, then shot lite coat, and then PPG clear lacquer over it. It all worked fine, if you get curdling dump it ! You can get in trouble doing stuff like this so do it slowly let it dry completely and most of all keep in mind, do it at your own risk

I fail to see the advantage to using Duplicolor lacquers, if you're diametrically opposed to using butyrate dope. For all intents and purposes, it is butyrate dope. The reason to use it is that it's probably cheaper than buying and shipping bottles of Brodak dope, and the color selection is almost infinite. You can put it over butyrate or under butyrate, and it smells just as much as butyrate dope. I like butyrate dope...and Duplicolor is on my + list.
I looked through my bookmarks and found the following. I'm not sure that weights and other critical factors were ever reported on some of the posts. Maybe they could be updated? ~> Steve
