Amen to Solartex-best thing to happen to scale R/C since the funnel. I have used several types of paint, sealed with PU to fuel proof. Works great. Only very slight wrinkling after a period of time, can be corrected by using a thin cloth under your sealing iron. It really shrinks tho, so stay away from the seams when tightening the fabric with your iron. Lower temp mentioned above is a good idea.
