As an adhesive, 5200 has far more holding power.
I just found out that the PO sealed up our fore-peak deadlight with 5200 when he got tired of dealing with leaks.
The deadlight is leaking.
I have a friend who is a chemist and loves a challenge, I will be contacting him for advice regarding th eremoval of 5200 (but I'll be trying the wood stripper that worked so well on the 4200 first). <hr height="1" noshade id="quote"></font id="quote"></blockquote id="quote">
From 3M:
3M™ Marine Fast Cure 4200 Adhesive Sealant One part general purpose polyurethane reacts chemically with moisture for flexible bonds to wood, fiberglass, gelcoat, plastic and metals. Forms a watertight seal on joints and boat hardware above and below the waterline. <b>Formulated to allow for disassembly of parts.</b>
There is a product called Anti-Bond. I ve used it several times to remove 5200-ed items from the boat. Be patient and work at it slowly. I use a very thin putty knife to assist.

Exactly my point, the only difference between the 4200 and the 5200 is in how it adheres. There is no advantage to using 5200 where you have a persistent leak. 5200 does not seal better than 4200, it only attaches more permanently. So if the leak comes back, as in my situation, you will be making more work for yourself.

I've heard that too! That's where all of mine are.

But I do have some thick books on this subject.
