Getting ready to build another Smith Miniplane and would like to make it even better than the first one. Especially the covering. I used white Solartex and red trim and plan on using Worltex (white) and red trim just like the pic on the box. Need advice as to what paint to use over Worltex and the best way to seal it. I used Varathane paint and clear spray to seal and wasn't real happy with the results. The sealer broke down , the paint faded and was almost impossible to keep the plane clean. Any advice would be appreciated.
