Amazing marine goop?

[ShoestringMariner]

Has anyone tried the “Amazing marine goop” in place of 3M5200?

I want to re-seal the keel bow-fold of my aluminum boat before I install the floors. (Apply a thick bedding where my rivets are as I had to scrape out a pile of it

I've used it, but I would never, ever in a million years substitute it with 5200.. Totally different products..

And fwiw, I wouldn't use it on a boat. I sealed a plastic rain containment barrel and yeah it worked.

3M 5200 is available at some home centers and hardware stores as tub and tile caulk. It is the same product with different packaging and a much different price

I couldn't find it at Home Depot this year, but I know a way out hardware store carries it.. I bought some at the marine dealer where I bought my boat trailer at the same time and they discounted it for me to $27 per tube.. It was there and I knew I needed it so while they sold the trailer for ~$500 under list price at the beginning of the season, they made up for it a little
