How long should I wait before I run a glow plane that I sprayed Rust-oleum Enamel Paint on? I did my cowl 3 days ago and was wondering if it would be fuel proof by now. I forgot the length of time I should wait.

What nitro content are you running? rust oleum is not glow fuel proof....more like resistant...the lower the nitro the better....
Your orginal question ....at least 3 days the longer the better.....

To be really safe467.5 days; or 3 if you're in a hurry. Three should be fine. Try to keep as much raw fuel off it as possible as it is not fuel proof, as stated by Jet.

I'll be running 10%. Raw fuel won't be hiting it, but some exhaust oil might spray a little on it from the prop wash. So I should give around 7 days to be safe?

I would say if it smells like fresh paint, it still needs to gas out.

Oberst

Nope, she doesn't smell of fresh paint going on 4 days as of now. But then again, my nose doesn't work so good anymore. I'll give it a week to be safe.

Thanks for the tip guys,

The longer the cure time the better, I even give LustreKote about 10 days.

If you read the fine print it says to avoid setting objects onto the paint for two weeks after application as it can still stick with enough pressure. I have waited a full month and had a finish that has lasted with no adverse effects to four stroke exhaust, and I did fly a cowl after 3 days and had some issues. The longer the better. I also found the metallic paints are not at all resistant even to exhaust.

Once you are convinced the paint is dry, i usually throw a coat of carnuba wax on it. I try & wipe the fuel residue off as soon as possible after flying. They'll look new much longer.....Gene

Depends on the color. I would wait a week.

Just curious. Why would color have anything to do with it ?

I've used red, white, black, yellow, blue, brown, and forest green, with good success. (FYI - Olive Drab is more like Forest Green) Normally I only waited about 2 or 3 days then flew. I used grey on the inside of a decathalon and had a tank leak that got 10% glow fuel all inside the cockpit area before I noticed it. During clean up, the grey paint just wiped off. The other colors did ok (on other planes) painted on fiberglass, ultracoat and solartex. No problems with the fuel. Later, I used the same grey on the bottom of a warbird but let it cure for about 3 weeks (mostly cause I couldnt get to it any earlier). Fuel had no affect on it. This was the bottom paint on the fuse and on the cowl with a pitts muffler pointed down. Didnt have any problems with the grey sticking on that. So I figured the extra wait time helped a lot. I've heard from others the clear is no good. I'm trying out warbird colors right now, like it a lot. The color pigment is very fine and there is a lot of it, covers real good. The rustoleum pigment is pretty course but still cover good and is a lot easier to apply in the rattle can. I havent tried rustoleum in my spray gun. The local lowes paint guy told me he could mix colors for me. We'll try that later on.

Got a bit confused by your last comment. What brand of paint has the "very fine color pigment" as compared to the Rustoleum which has "course color pigment"?

The name of the paint is "Warbird Colors". http://www.warbirdcolors.com/
I've bought from him several times. He'll do ya right.
