That it’s the best
This is the best sealer ever, it will stick to any thing and last for ever. I have used 20 years ago as sealing around my new windows and it is still working very good. Thank you kencountryman

Damaged/missing cartridges
OSI Quad sealant is a great product which I've used for years. Ordered five cartridges but only received four. The four cartridges received were dented and the plastic tips broken off two of the cartridges. Making them pretty much unuseable as I can not put them in the caulk gun nor being able to us for caulking edges. The ones with broken tips I sliced the cartridge open to put sealant on door jambs being installed with a putty knife.
