I have found as a general rule the more durable the paint the higher the toxicity. Waterborne paints are a prime example. Warnings have existed for years not to confuse environmentally friendly with free from health risks.

The only safe way to deal with any paint is to obtain the MSDS (Material Safety Data Sheet) and educate your self to the dangers and take proper precautions for use of the material.

Paints never intended for spraying that include additives to enhance flow; self leveling and drying times may have added risks the manufacturer has not considered.

I remember in the tool trade there was hand tapping compounds that were the best but guys were using them for power tapping, drilling and cooling mill cutters. When they were heated they broke down into extremely potent carcinogens. Used as per the instructions there was no hazard.

It does not take long exposure to develop extreme sensitivity to the chemicals used in these paints. Please be careful and enjoy your hobby for a very long time.

Re: What do you use for nitro and gas proof paint

+1 on Klass Kote epoxy paint I use it on my boats with 50%-60% nitro and I can spray it with an airbrush or small gun, but most of the other guys in the club use auto clear coat.

Re: What do you use for nitro and gas proof paint

I agree with Dennis (Lazy Ace) that the most durable - and quicking drying/curing - finishing coatings seem to be the ones with greatest toxicity.

That doesn't mean you should/want to always avoid using them but, as Dennis said, dig up the ingredient's sheet online and use them safely.

For me this means brushing and using them, as much as possible, outdoors.

Re: What do you use for nitro and gas proof paint

It goes much deeper ... even cleaning high quality paint applicators requires some very dangerous and highly volatile cleaners. Even with a proper respirator mask, gloves, even clothing ... accidents happen. The data sheet will speak about safe storage, something few hobbyists think about.

Some of the cleaners will eat right through your latex gloves, some masks and eye protection fail completely from the overspray. They will do wonders to your kitchen and laundry room pipes! Hope there are no plastic parts in your spray gun / air brush!

There is an artificial "safeness" created by so many of those TV shows where the guy shown with the paint is spraying happily for the four seconds the shot was being made. The real paint was applied by a guy who looked more like an astronaut!

... and don't miss the section on proper disposal.

Re: What do you use for nitro and gas proof paint

My models are generally gasoline powered. For the scale models I use Latex house paint. Easy to spray (thinned with some window washer fluid) and with a little common sense will not put you into the hospital. Latex is NOT nitro fuel proof. Roy Vaillancourt has used latex on Top Gun quality scale models for years and it gives a durable finish.

Check out the articles on his website:


scroll down the page to the articles section for the two part series on painting models with latex.

Re: What do you use for nitro and gas proof paint

EXCELLENT input guys. Lets hear some more about your experience with different paints. Good or bad. The safety tips are extremely important. Having sprayed before, I know the dangers, but did not consider that others may not. I am working out of my garage, with exhaust fans, but sometimes cut corners on P.P.E for convenience or laziness or whatever. Thanks for re-educating me.

Re: What do you use for nitro and gas proof paint

I use Topflite Lustrecoat comes in spray cans, and comes in many colours. You can pick it up at your LHS. I use a north half mask in a spray booth with exhaust fans. The stuff is deadly if you don't wear proper PPE. The nice thing with this paint it dries quick because of the benzyne that's in it. 2 minutes between coats. It works very well.

Re: What do you use for nitro and gas proof paint

I just get it at my local paint store; Auto Home Paints. Pretty much anywhere that sells real automotive paint should have it....

I think it's about $25 a can. Not cheap, but if you do automotive work you go through this stuff like crazy anyway. The larger can will harden about a gallon of paint.

Re: What do you use for nitro and gas proof paint

I have been playing with west systems 2 part epoxy. I use mostly black gelcoat tint paste in the epoxy and then add the hardner. Sometimes the finish is ok but sometimes there is separation of the tint. Looking for tint without the plasticizer. Might try graphite next as a tint agent. I fuelproof the firewall for all my nitro projects. So far great fuel proof results and added strength so there is no crush in the ply with the mounts. Anyways... thats my direction of experimentation.

Re: What do you use for nitro and gas proof paint

Endura all the way. Some suppliers are willing to sell you small quantities like an 8oz can with the part be in a separate jar. My friend runs a paint store, which is handy... Barring that, go to an auto body shop and ask nicely for a jar of some left over ppg and hardener. Can usually get some for a few bucks.
