I have to warn y’all off of this stuff. I started using it a while back, until my IOM sank for no apparent reason. Turns out that the stuff is very UV intolerant and degrades quickly outdoors (no direct sunlight needed!). It looks OK but becomes brittle. If your boat is bumped (yup, just a little shock will do it, no need for an actual boom-end to poke a hole), an almost-invisible micro-split can turn into a gaping tear within minutes. That’s what happened to me, I found out afterwards…
