It’s time to think about the exterior of my squaredrop. My sides are 5/8 exterior ply. I plan on covering them with something. I’ve heard that HD brand of RFP will deteriorate rather quickly in the sun. I have heard that there is a UV safe FRP. If anyone has information on uv safe FRP, please let me know. Otherwise please chime in. If I end up using big box FRP, then 2 questions. What adhesive
shoud I use to avoid de-lamination, and if I paint it, do I have to prime it first ? What paint works well on FRP. I know all this has been asked before. Filon would be my first choice but I’m trying to keep my first build in the budget. Thanks.
