Don't use the epoxy paint. This is a single part epoxy that will not cure until the solvent evaporates, this takes a long time. Even then It is not really that good compared to a two part epoxy. Better to use the Duplicolor car paints, check the back of the canto make sure you are useing an acrylic lacquer. These are fuel proof to about 20% nitro.There are several products that are acrylic lacquer, the perfect match is probably the most common.
