I tried it last year and in spite of the muffler having about a week to cure which was way longer than the mufflers back in the day got, the paint went sticky and started to streak the airplane.

I assumed they changed the formula.

I bought and tried a box full of cans, every brand I could find. Every one got 3 or more days to cure and every one of them failed. Only the first couple got tested on an engine/plane. The rest just got some fuel spray. I've read since that some of the brands I tried worked for others. Got no idea why, none worked for me.

Finally I just painted it with the color I wanted. Once that paint had cured, I coated the entire thing with acetone thinned 30 minute epoxy. A little really went a long way. Applied the epoxy with a latex rubber glove and my finger. It gave the cowl a beautiful high gloss finish, the color hasn't faded, and paint hasn't softened or peeled in over three years.

Status: offline 		I once found different paints that were fuel proof and then the paints must have changed because they quit working a few years later. I can still find Ultra and black Barron paint once in a while at one hobby shop, How old it is?? Not a clue but it works. Luster is still sold in shops and at Tower, the colors may be off a bit, sometimes way off! It tends to run but it is fuel proof.
An OK HVLP spray gun can be bought at Harbor Freight plus a touch up gun for only a few bucks, even a single stage Air Brush. They have a very cool item for about 10 bucks too, it is a can, you put in your paint and just pressurize it, SHAZAM!!!!!!! Instant rattle can with the paint of your choice. You still need a small compressor at home though but HF even sells those!!

Status: offline 		OK The basic colors of Rustolium are fuel proof, to 15% at least - red, yellow, white, black,etc.. Not the metalics, not the clear. Krylon polyurethanes are fuelproof - I don't think the others are. Let Rustoleum dry for several days or longer. Remember, you cannot put just any paint over any other paint. Try a small spot for compatibility. You can always paint a piece of cardboard, let it dry for while, then put fuel on it an let it set.

Status: offline 		My brother painted a Super Sportster with Rustoleum several years ago and it seemed to be fuel proof. It was so long ago that formulas could have changed.

We painted my Corsair with LustreKote http://www3.towerhobbies.com/cgi-bin/WTI0091P?&C=RHQ&V=TOP and it is fuel proof. They do not have a huge selection of colors any more. I wonder if the clear would go over other brands without causing a reaction. If yes, you might be able to use Krylon or Rustoleum for the color and LustreKote for protection.

Status: offline 		I'm just about to buy some Klass Kote clear, the two part epoxy will go over pretty much any paint to fuel proof it. My next plane is a glow powered but I will be using water based Latex from Lowe's so the KK will work great over it. I will use a cheap HVLP spray gun though. I also want to try using gold leaf and the KK will go over that too. If your using a gas engine then you don't need to fuel proof latex paint. Looks good and it's cheap, can also be mixed and matched at any hardware store.

Status: offline 		Krylon polyurethanes are not necessarily fuel proof. If it's a water based poly it's definitely not. Oil based may be, but they will also yellow with time. For future reference, some auto paint stores have a 2 part urethane in a rattle can that you activate just before spraying. It will be fuel proof and won't yellow or peel over time.

Status: offline 		I used Rustoleum automotive clear coat and it seems to be pretty good. I had painted 3 coats on a piece of ply, let it cure for a day and then put a blob of 15% Wildcat on it and let it sit for a day. It wiped off without any softening.  I painted the bare parts of my Eflite T-34 with it and haven't had any problems....yet.

Status: offline 		Lots of paints will stand up to raw fuel, but then soften when they get exhaust on them. The real test is to put a painted panel in the path of your tailpipe and run the engine for about two minutes. Then let that panel sit for 24 hours with the residue on it. If you are still able to wipe the residue away and have no staining or softening of the finish, you're good to go.

Status: offline 		I made a stop by the locale shop and picked up some silver lustercoat, Ive got every thing masked off now and have three coats on the alirons now and two coats on the tail surfaces with one more coat to go. I really think this is going to turn out nice. I will post pics of the completed job when done, Im thinking next week she should be ready to fly.
