I am spiffing up a well enjoyed Goldberg Skylane and the windows look terrible. The canopy glue has yellowed and castor oil has been collecting around seams since I started flying it. I'm thinking a bead of white paint about 1/4 inch wide around the edges will hide the mess when I reinstall the windows, so my question is what to use? It has to be fuel proof and it has to stick to acrylic. My first thought is to mix some white tempura paint with clear epoxy, but I'm open to anything simpler.
