I’ve heard good things about the West Systems epoxy, but, never used it. The cracks I’ve glued up were repaired with 3M products, usually 2216 structural adhesive, as it was easy to find, locally. Very generally, I don’t find Isocyanates to be as durable as quality, name brand epoxy.

You don’t get good epoxy at Harbor Freight.

I’ve had about two repairs on wood that convinced a few I was a genius, but, I was more likely very lucky and got to it before things got worse.

That’s all I’ve got.

Best,
Ted
