Dose any one know if auto (plasti-kote) epoxy paint is fuel proof and also is enamel paint fuel proof or should it be sealed with clear coat.

I didn't know that epoxy paint was used in the auto industry, but epoxy is fuelproof, so that shouldn't be a problem, enamels and urethanes should be mixed with their respective catalysts, hardeners, that makes them probably one of the best choices for painting, there are some synthetic enamels (Nason) that use a catalyst, which are very inexpensive in comparison to the other two, they are used in the auto industry on cheap paint jobs, but for model use, they are fine, although, they don't recommend to spray clear after the paint has cured (usually 24 hours).
But any of these finishes, in my personal opinion are the best for model use, long lasting, fuelproof and shine forever.

strong,

I don't think that Plasti-Kote is really epoxy. There are a number of spray paints ( might be available as non-spray as well ) that are called "epoxy enamel" or "appliance epoxy", or other things, that are, evidently, not really epoxy. Most of them seem to be some kind of oil-based enamel. They might be just fine paints, but if they aren't two-part, they are not epoxy, I have been told. Whether they are fool proof seems to depend on the brand, etc. There have been a number of threads here about paints. Do some searches, and you may find that someone has tried the kind of paint you are thinking about.

Plasti-Cote is not epoxy, I don't care what is says on the can. It is impossible to have epoxy paint in a rattle can. The science behind epoxy paint requires a chemical reaction when two chemicals are mixed which cures the paint.

So the spray can enamel is fuel proof and also the epoxy paint which can also be used on appliances is also fuel proof right.

Not all enamels are fuelproof, epoxy paint (two part) are fuelproof, but you will not find them in a can, ACE hardwares have a spray can epoxy (their own brand name) that is fuelproof though, and sprays very well and gives an incredibly good finish (for a spray canned paint). You have to be careful with spray canned paint, always test if not sure, Rustoleum is fuelproof, except for their silver and clear.
Some spray paints in a can are said to be epoxy, maybe they are, maybe they are not, any chemists out there?

Spray can epoxy ? Not likely. The epoxies I know require two-part mixing or heat cured (has to be stored in freezer before use). The spray can "epoxy" implies that it is moisture cured but that can't be epoxy. I think what the manufacturer is trying to say is that it is "epoxy-like". Just my 2C..............

Strong,
I have read that several modelers use Rustoleum paint and claim it is fuel-proof. I beg to differ, depending on your nitro content!
I did a test and found that 25% nitro will eat through it!! You can use some cheaper spray-bombs and then clear coat with Lustre Kote, but it is only good to 15% nitro. For true fuel-proof applications with higher nitro, use a two-part automotive paint or K&B epoxy paint (available at www.modelengine.com).
