Boat Sealant Question

[Fester]

I have a Bass Tracker Bantam 2X and need to seal the seam between the top and bottom pieces. I do not have a problem spending the money if I have to on Marine sealant but if there is another home or business product out there that is comprable I would like to know what it is. Does anyone have any information or advise as to what I can use outside of 3M 5200 Adhesive Sealant. Thanks in advance!

i would not use 3M5200, i would use 3M 4200. get it in a caulking tube.

Ditto. DO NOT use silicone at all, it won't hold more than a few minutes.

3m 5200 is probably what was originally used, or something close. 4200 is just as good but slightly less permanent. You can probably get by with one or at most two tubes for that boat, cost maybe $20 total.

What is the difference between 3M 5200 and 3M 4200?? I found the 5200 for $16 for 2 tubes. Will there be a problem with sealing the boat with pop rivets and then finishing up with 5200? If so then what is the problem with it? separation? strength? longevity?



Thanks for everything

That's probably was it was originally sealed with at the factory.

5200 is designed to never be removed. It'll seal/adhere, and then some. If you try to pull it off, the fiberglass/wood/whatever it's attached to will almost always fail before the 5200 will.

4200 was designed as a less permanent variant of the 5200, with all the same good characteristics but an ability to be removed if needed.

Using either one, don't just patch what's there... separate the hull fully, clean up the joint, and re-attach. Neither one will work well if you don't clean out the old junk thoroughly.
