Status: offline 		I am going to paint a 2 liter coke bottle for a cowl on a plane and would like to know what or if any brand of spray paint is fuel resistant to glow fuel. I thought I heard that maybe krylon or something like that is. Thanks for the help.

Mostly the Truck and Van paint is acrylic laquer, read the back of the can to be sure. You can find Plastikote in automobile stores. A plus is that it dries fast and doesn't run easily. BTW the Monocote paint is also acrylic laquer.

Status: offline 		Painting coke bottle can be difficult. Any paint that is fuel proof may dissolve the bottle. I've not had good luck with Rustoleum or Krylon for fuel proof. The Lustrecoat dissolves the clear plastics.

One technique to try might be painting it with rustoleum, and then putting on a couple thin coats of finishing resin. That will add a nice high gloss, and its fuelproof to boot.

Status: offline 		If a paint STATES ON THE LABEL that it is an acrylic, there is 95%+ chance it is fuel resistant. To be certain do a test panel, then do a raw fuel test (pour some fuel on the panel and let it sit there for 5 or 6 hours, then wipe off). If it passes the raw fuel test, then do the exhaust test. Hold the panel about 10" - 12" from the exhaust of a running engine for a tank of fuel (about 12 minutes). Make sure the exhaust is going directly on the panel (a pair of gloves is nice to keep your hands from being burnt) during the test, then let the panel sit for 5 - 6 hours before cleaning.

BTW - Not all colors of Rustoleum are fuel resistant, and the ones that are typically need 3 - 4 weeks (or longer ) of drying to develope fuel resistance.

Status: offline 		Thanks all for the help. I'll try Rustoleum and do a test area with raw fuel and with the engine running for 12 min. time and wipe the area to see if the paint stays.

Before spraying the coke bottle cowl, should I sand the the area to be painted with 200-300 grit sand paper to roughen the area for the paint to adhere better ?

Thanks for all the great advice

Most acrylic paint is either acrylic latex which is somewhat resistant, or acrylic enamel which is not at all fuel proof. Only acrylic lacquer is truely fuel proof.

I am pretty sure the large coke bottle bottoms are resistant to most acrylic lacquers. Try a test coat to be sure.
