The stuff peals off quite nicely and appears to leave no nasty residue. If you are concerned about appearances perhaps you shouldn't put a hole in your kayak...

: Looking in an RV catalog, I see Eternabond White "designed for
: maximum flexibility, durability and UV protection. Eternabond
: White will never crack, peel,
: harden, ooze, or lose its grip."

: 6" x6" patch ~ $16.95
: 4" x 5' roll ~ $28.69
: 4" x 25' roll ~ $62.95
: 4" x 37' roll ~ $102.85

: Seeing that it is white, it might look better for the long run on a
: fiberglass boat with a white bottom (where most penetrations
: occur).

: The silver says its for "any surface where tensile strength is
: desired and flexibility is not essential".

: Next time I go by these guys, I'm going to ask for a piece of white
: for the test.

: What gets this stuff off once used when the repair needs to be done
: ?
