: Now that I have two thin coats of colored epoxy (US Composite) on my rec
: kayak, I'm curious as to how many others have used epoxy to seal the skin.
: It sure seems to work great. The test panel that I made a few months back
: with nylon and polyester cloth both hold the epoxy very well with no signs
: of delam or cracks. Any drawbacks?, other than it may be difficult to
: remove the skin to replace or that I still need to varnish anyway or that
: it's too heavy. Any other penalties? How durable is it? Thanks in advance
: for any help.

Don't do it. The epoxy may look good on a test panel, it won't work on a functioning skin. While epoxy has some pliability, it won't be nearly enough to keep with the flexing that happens to a skin on frame when it's being paddled. You'll end up with cracks that will seep water into the boat. The polyurethane or paint most folks use work by permeating fully into the skin and has the ability to flex with the skin to maintain a water barrier.
