: I have 10 year old Raka resin and non-blush 350 hardener. Left
: overs from when I built my boat. The bottom of the kayak had not
: real damage, but 10 years of use...dents, scratches and keel /
: bow issues.

: I sanded the bottom through varnish showing a bit of weave. I need
: to fill a couple small spots where wood is exposed. Once these
: issues are taken care of, Im thinking about a think skim coat of
: epoxy on the bottom before re-varnish.

: question is...any reason to avoid using 10 year old raka epoxy?

Hi Chris,
It should be fine. I've just done a wee bit of epoxying with 7-8 year old WEST and it's turned out as well as the parts I did when it was new.
If it's stored in good conditions, I don't think epoxy actually goes bad. But do a small test piece for colour, mine is a small bit darker but that could be the difference in the timber colour.
