"Silicone-based sealants have very few legitimate uses on a boat."
Offhand I'd agree with you, but Mark Plastics, who are one of the larger players in replacing OEM glazing on a lot of older boats, specifically say to use silicon seal to bed plastic portlight surrounds into the wood/fiberglass hull of a boat. Damfino why, I like more permanent solutions.
