Putting a new fuel Tank in 23 ft

Bayou - Was that question for me? Here is what I learned from another boat site (tolman - fishyfish.com):

I can't seem to tell the difference between PL Premium Polyurethane
Roof and Flashing Sealant and 3M 5200 Marine Sealant. The Pl is
about 1/3 the price so I've been using it. The only downside is the
I've only found the PL Roof and Flashing sealant in black color.
It's every bit as messy as 3M 5200, so it pays to mask off all the
non sealed areas.
