: Wilderness Systems recomends a product called "Lexel" to seal the
: Minicell foam bulkheads in their polyethylene boats. It's supposed to stay
: flexible and will stick to itself. (unlike Silicone)

: Anybody used it yet?
It is a very good ,may be polyurathane type caulk, you can get at better lumber yards. I have used it and has great glue properties. Very reliable but almost to thin, I'd do half of the fillet at a time, but a test would tell,may have thicken product,been a few years.
