e-Bay is a place to dump stuff. Who knows what they are selling. Epoxy can come in a gazillion different mixtures. You won't know what you bought until that e-Bay seller is long out of the picture.
Since none of us are chemists all we have to rely on is the reputation of the maker. None of them does business on e-Bay. They don't have to. They have a reputation that guarnatees their success.

: I thought I'd open up another thread. The link below is a brand of epoxy that
: is on sale on ebay. They have pictures of a kayak that has been epoxied
: with this stuff.

: The epoxy is called "EPOXY RESIN FIBERGLASS CARBON FIBER KEVLAR MAX CLR
: HP"

: Has anyone used MAX CLR-HP? When I did a search on ebay I found this item for
: sale (1 gal resin + 1/2 gal hardener, for about $85usa) Just wondering how
: good/reliable it is.
