RE: Cowl Paint?
No Special prop required. Paint on the cowl needs to be "hot fuel proof" and can be purchased in spray cans at the hobby shop. Regular hardware store paint such as rustoleum and other brands is sometimes resistant to fuel, but not 100%. Even the so-called "hot fuel proof" will get messed up over time if you get a lot of fuel on the paint. High nitro fuel is especially bad on paint.
