I used to paint mufflers with one of the brands you mention back in the day. Used the high temp stuff.

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.

I was trying to paint a cowl a few years ago, and tried all the over the counter spray paints. Nothing worked. All started to peel and soften within a few days of flight. 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.

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!!

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.

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...P?&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.

I have used model master paints over Monokote and then cleared with Luster coat. I had it laying aroung so I used it. Not my first choice but it works.

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.

I had very good luck with spray-paints meant for car engines. Not very many colors available but they are 100% fuel proof.

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.

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.

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.

So far the Rustoleum CC is holding up. Had a couple flights on the plane I used it on and it cleaned up well.

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.

Can someone please define what the "Basic Colors" of Rustolium consist of since people are saying they're fuel proof? How about listing specific products with names from, say, Walmart.com? I know Walmart sells Rustolum paint off the shelf, so that's why I'm asking. Thanks!

Sorry but no Rustoleum is fuel proof. The Appliance Epoxy holds up fairly well but only come in white, black and beige.

Please scroll up and read the comments on 8/13/2012 @ 12:14 PM from RCPAUL He states: 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.

Please understand that the issue with getting help with these forums is that you can't tell who knows what they're talking about and who doesn't.

I agree that it is difficult to see what peoples experience is on a forum. One reason why when giving technical advise I usually state my piece and then leave it alone. I can however assure you that if you paint a wet fuel model with Rustolium or Krylon paints and expect any level of a paint job you can take pride in, you will be disappointed.

Huum,,, I have many planes I've painting with Rustoleum and Krylon, a few painted with Latex too,, I've been successfully using these alternates to hobby paints for almost as long as this thread is old and I take pride in each and every one of them.

Now these claims that Rustoleum is glow fuel proof,, I tend to doubt it also,, I always use a clear coat I've tested to be glow fuel proof on the couple glow planes I still have

When is doubt,,, test for yourself

Correct me if Iím wrong here Tom but arenít those scale warbirds that a show auto, glossy type paint job just wouldnít look the part? Of course that along with expectations plays a part. I suppose I should have asked what type of airplane was being painted. As you know, on most of my stuff I want the nice high gloss finish.

Not everything I do are flat or satin sheen warbird schemes

White Krylon Appliance white of the fiberglass fuse matches the Ultracote pretty good



Grey, Red and Black is rattle can Rustoleum,, Yellow is color matched Latex with Gloss clear, Satin Clear over the black anti glare panel



This one my buddy restored and recovered,, I own it now, flew it today actually, Rustoleum matches the Ultacote red pretty good too


Also all rattle can paints although this one is EP



So yeah,, I'm plenty proud to own all of them
