Putting a new fuel Tank in 23 ft

[datngrizz]

The link above kinda bugged me...wouldn't it be better to run the strips the length of the tank with 1/4 inch or more before the end of the tank? That way water would run down the length of the tank/plastic and not have the plastic act as a baffle? I am only askiing because I will be putting my tank back in in a couple of months. It tto sat on t he deck of the coffin with no spacer under/between it and the fiberglass. Any others with experience/recommendation. OBTW, any other spacer material recommended besides Haysite? THX!

I used Lexan with 5200 per the link instead of Hysite.

Did you go the length of the tank or width?

My plan is to run 5-7 1/2" UHMW strips under the tank. I can't decide if I want to 5200 (well, actually PL roofing silicon since it's the same stuff chemically and about 25% the cost) the strips to the epoxies plywood or tank itself.

Are you talking the PL-1 stuff....it's an polyurethane expansion joint compound...

I am going to go the length of the tank

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.

Yes thanks....I've was also thinking of the NP-1.....
not PL...
