(SNIP) I have seen boats from four different major manufacturers that degraded to the point where the finger test failed. In defence of the manufacturers all of the boats were built during the days before Vinyl ester resins. So, the resins used were probably Isopthalics at best or orthopthalics at worst, The failure (Steve Freund can correct me on this if I am wrong) is due to the absence of UV stabilisers in the resin. In my day UV stabilisers had a purple color and people didn't like the look of them. Hank's experience not withstanding clear resins do not appear to perform as well as pigmented resins.
