Before you commit yourself to this project you should be able to answer Sam's question. Kevlar doesn't just crack. DuPont claims it's 10 times stronger than steel by weight. If it was involved in a bad pile-up, like getting wrapped around a rock, it may have suffered the kiss of death. Patching it up to keep the water out is a slam dunk but if the hull is jacked out of shape it's going to exhibit some strange characteristics.

: Hi Folks, my brother-in-law has just acquired a We-noh-nah kevlar canoe.
: Unfortunately there is a crack running through the gunwale into the bilge
: area.
: My question to those in the know, Can I repair this damage with fiberglass
: and epoxy. It appears that someone has made repairs that look like they
: used the type of fiberglass that we use on our boats. Will it stick if I
: rough it up and prep the surface. This needs to be a low budget repair and
: as I already have lots of leftover glass and epoxy I would like to use it.
: Unless there is some problem doing this. The boat is well used and has
: quite a few modifications done to it so appearance is not much of a factor
: here. Any info or links to info would be appreciated.
: Keep building, Elliott
: BTW the boat is an amber color if that helps. I will get a pic of the thing
: when he drops it by.
