I'm replacing the deck on this boat. The front livewell has an access hatch in the deck, the livewell plastic tub is actually pop-riveted to the aluminum stringers, and there is a putty-like "tape" (flat, 1" wide, 1/16" thick, uniform width, flakes off like putty when pulled up with fingernail) around the rim of the tub that must be the seal between it and the deck that contains the hatch. Would peeling this old seal off and just using a thick bead of 3M 4200 be an acceptable alternative seal between the livewell and the deck? Thanks.
