I got the idea after fuel proofing the fuel tank area with epoxy thinned with alochol. This was suggested by some members of my flying club. Later I got to thinking why not paint and then fuel proof the surface in the same manner as I did with the fuel tank compartment. And the rest of the plane is surfaced in monokote. I'm only trying the control and stabilizer surfaces. The paint i used is ordinary car paint obtained from my local car parts store.
