Not all epoxy resins and polyester resins are compatible. Before proceeding with the whole project, it is a good idea to do a small test on the inside of the part. The wheel pant in the foreground has been sanded and is ready for covering. Even though you can see the weave in the glass, you cannot feel it. The other pant has been coated with resin but not sanded.
Resins cure to a high-gloss finish and are easy to sand.
When working with a compound curved surface, iron the film onto the highest point of the curve first. Once attached from end to end, the film can be heated and stretched around the milder curves. On each pass, heat the film until it becomes rubbery, stretch it until it conforms to the part s shape, then press it down onto the surface. Note the position of the iron. I am heating the film in the area that will next be stretched into place.
