If you are suggesting that direct sunlight will not break down epoxy resin, you must be joking.
: "If your project is not in direct sunlight, I don't think you have anything to worry about. Direct UV exposure should be avoided. If morning or evening sun is casting direct rays onto your project, even if for only a few minutes a day, you should cover the exposed parts with reflective material."
: You are joking, right? Most of the professional builders suggest that after finishing all the epoxy work, that you move the boat outside on a hot clear day to help the epoxy reach a final cure. Also, one of them suggests this for up to a month before he will even begin priming and painting. It lessens the chance of the fabric showing through the epoxy and paint.

: : : I know that sunlight will cause problems with epoxy. I am in the hull construction phase now. My Glen-L 19 is being constructed in a garage and has never seen the direct sunlight. I am concerned about the amount of time I have before I need to worry about sunlight effecting the epoxy glue joints. The frame has been under construction now for a couple of years (had to take time off to move). How long do I have before I need to get the frame vanished with UV protection?
