Low cost fuel proof spray paint
« on: March 02, 2006, 10:37:12 PM »
Hi All,
This is my first posting at the Stunt Hangar- I'm visiting from the SPEED FORUM.

My question involves use of low cost commonly available spray can paint as a model finish.  Now that nitromethane content is down to 10%, is it true that there are paints(possibly water based poyyurethane) that are fully fuel proof?

Inquiring minds want to know-

Thanks, Will Stewart

the answer  is  NO  they are  not  fuel proof.
The only real fuel proof paints  even  for  10% nitro  are  2  part  paints

I am talking about fuel proof not  hot  exhaust oil  proof

I am not sure if this is what you are looking for?

This is what I use to paint most of my control line planes. ( If I don't cover them all in monokote) :P

You can get it a Wally World aka Wal-Mart.

I have had good luck, many years ago, with oil based polyurethane.  I don't know if it would qualify as "hot fuel proof" as Pactra used to say, but it held up as long as my aircraft, for what that is worth.  Russell

In my opinion, no paint is completely fuel proof to raw fuel.  The methenol and nitro is what hurts.   Now the residue that comes out of the exhaust should not hurt a good poly-urethane clear.  I do finish most planes with a 2 part automotive which requires a great paint mask and air moving the spray away from you.   Later,  DOC Holliday

Any Rustoleum color except the metallics, and clear, are sufficiently fuelproof (OK, exhaust-proof, who soaks their planes in raw fuel anyway?) for our purposes.  I have planes several years old painted with Rustoleum, just about flown to death, no softening yet.  Good enough for me.

what do you put down under the paint on raw wood before using this paint?

I don't know about others,  I use Rustoleum flat primer on the bare wood, usually 2-3 light coats, sanding between, then a couple of light coats of color, that's it.  DO NOT try Rustoleum clear for a top coat--it doesn't even pretend to be fuel proof; likewise the metallics.  Too bad 'cause they sure are pretty.

I have had good luck using the cheap brand at Home Depot. I think it is called Americas best or something like that- but it is made by rustoleum.  look at the small print on the can down near the bootom- If it say manufactured by  R O C, that mean Rust-Oleum Corp.

It's about 2 bucks cheaper a can, flows out pretty good if you warm it in hot water and shake the bejeezers out of it. I use the same brand sandable primer underneath, sanding all of the 1st  2 or 3 coats off, then lay down a good coat and sand with 200- 400.  A couple coats of color on top and let it dry for a week. I use Powermaster GMA blend 10% - and as long as I wipe the plane down after flying i have not seen any damage.

Of course my planes don't get a lot of flight time, mostly they hang in the garage and wait for me to come home- but the paint is still good.

I dont know why I didnt mention this before, but I have used epoxy paint for appliances to good effect in the past. I first painted a muffler black with this appliance paint, and the paint is still intact. I put some 25% nitro fuel on it after it ahd dried, and the paint did not even soften.

The down side is that it is heavy, and I have only found three colors: black, white and biege.

The good thing is that it only takes a minimum number of coats to cover.

I would not use this on a contest plane, but for a practice plane or a kids trainer, it should be great.

So if you think black, white or biege is a color you want to use, try it, oyu might like it.

I wonder how well Rustoleum will hold up to high nitro fuel. I have been using 30% heli fuel in my TD .051. I have a new plane ready to cover and paint and I would like to give Rustoleum a try, but would hate to have the paint start coming off the first time I wipe the plane off after a flignt.

Probably the safest bet would be to finish a scrap let it completely dry and do an overnight dunk test in the fuel you plan to use.

I understand it can take some time to completely cure.
