RC:
I use automotive paint, in particular acrylic enamel. I find them better than butyrate and as good as epoxy paints.Good coverage, light but takes a little long to dry. You would want to make sure to paint in a clean area. For primer I use Lacquer enamel, great cover, sands easily.
I also use Urethane enamel (dries quick) with same primer as above. I find it better than acrylic enamel and it dries faster with a harder surface.
In either case, make sure you use the reducer and the catalyst (hardener) to ensure fuel proof. I use 20% nitro content fuel. No clear coat required. These are "Martin-Senour" paints.
I buy these at NAPA auto store, but lately the Urethane enamel is getting difficult to find. I find these auto paints to be cheaper than PPG Concept paints and the epoxy paints.
Be careful with the colors as some contain lead, read the labels before you buy and have the proper personell protectection equipment when you paint.
