removal of Stainless Steel Cutwater

Hi, I don´t know exactly without seeing it, but cut with a carpet knive and heat the piece to soften the glue could be a solution. Hair drier or paint remover as heater.

tball,
The 5200 is very tough to get thru or take apart. Cut/score with a sharp knife like AMG suggested but you may have to "saw" through it also. I've heard of folks who have used piano wire or the like to saw thru the 5200. Not sure what angle or access you may have to do that. Scoring should help prevent pulling off the paint.

3M Does make a solvent for 5200 not seen very often but it does work even if a little slow

Debond is the solvent to remove cured 5200. Find it here; http://www.debondcorp.com/ It works very well.

What does Debond due to the paint finish? Any discoloring or blistering?

I would certainly mask the work area well to prevent surprises. Beyond that, I'd say read all of the fine print on the product.

Debond won't hurt the paint. But my 2 cents is that you're probably going to have to do some paint work on that area anyway. You'll likely find that the stainless, aluminum, and salt water aren't very good friends.
