I like boat life and their life caulk and seal. I recently bought a few tubes of the caulk. I had one that wouldn't adhear worth a ****. Peeled off like painters tape. The other tubes (which I then had to test because of the first one) was fine. First time I ever had an issue like that. It was an older lot number but still within usable range so just check that before you commit.
Are these through hull or blind holes?
