''''solartex is fuel proof but you would be ahead if you clear coat it. Cause if you get it fuel soaked it is hard to clean. If you have wrinkles in your solartex just iron them out but turn the temp up a little higher won't hurt a thing except for the paint if it is painted. I've got a TF P-40 with a Mag 91 fourstroker in it and cann't wait for the next flying season to fly it. Isn't quite done yet plan on painting it jet black with redish orange on the canopy and control serfaces. Fixed gear and no flaps was one of those swap meet things so went with what I have.
