Forgive me - I am a little confused about posting. I wanted to reply to the epoxy application issues (bubbling & Pinholing issues), but can't figure out how to reply. So I just clicked "post new" until I get a handle on this. My response to their problem was to advocate spraying epoxy rather than rolling. Spraying equipment is not that expensive at Sears. Even a Wagner sprayer works better than rolling. Spraying vs. rolling -no comparison.
Since I am new I should mention that I like kayaking, but me an my boys prefer the challenge of making it down the kaydeross creek in a canoe - into saratoga lake (Saratoga Springs NY) without capsizing. So far we are 0 for 4.
Speaking of coatings i discovered a great tough and slippery coating that slides over rocks better than anything I have tried. It's what the airboaters are using to slide over dry-land with - checkout-- www.airboatcoatings.com
