Maybe, but read it carefully before buying. Most of those are
polyester resin rather than epoxy. Every time I've looked for
epoxy it's cost a lot more.

Epoxy is stronger and safer to work with (less likely to cause a
chemical sensitivity reaction and less vapors) but more expensive.

It kinda depends on the quantity I can buy. I don't need to rebuild a
boat hull - a couple feet of mesh will do me plus the small amount of
resin or epoxy. I know the auto parts place had about what I need for
maybe $15 total.
