My SUPs are all Jimmy Lewis boards but there is something in the epoxy that protects against sunlight. I have some that have been leaning against my shed outside for over 5 years and they still are good, can't tell the difference between the side exposed and the down side. They do get sunlight but mostly shaded. The board I use I keep on my car rack pretty much 24/7 for the last 2 years. No Problem.

"I remember South Africa in the late 70's, sleeping on the beach at J-bay, smoking ganja with the blacks. On weekends we'd go to the pub in East London to drink beer and fight with the Afrikaners. They liked to fight, I liked to fight. It was a good time"
