3 oz Marine Adhesive Sealant 4000/4200 Fast Cure UV (White) - Sem-Permanent, Flexible Bonding and Sealing - UV Resistant, Above & Below Waterline - Compare to 06560 and 05260 FC M - by Berkland

Bought because it was less than 3m 4200 but with same characteristics. Worked great. Time will tell how well it holds up.

I like the ease, abusing the product.

Not What I Expected. While under the boat to install sixteen #8 screws I was squirting the sealant/adhesive into the first pilot hole when the top of the tube collapsed in my grip and I felt something on my arm which was the sealant oozing out of the bottom of the tube. The tube bottom end appeared to consist of nothing more than being folded over twice.Luckily my local Ace Hardware store had some 3M 4200 in stock.

If you have a boat, the #m products are the best !!!

Glue held but the tube split open just by squeezing with fingertips

First order didn't include gloves or the plastic tip which was disconcerting. Was able to reorder and return the other in one step. Second order had everything I needed so was able to caulk the gaps I had scraped out and luckily in rained that night. Found no water leaking the next morning so fingers crossed the caulk sealed the problem area.

I may have purchased this years ago and have the same gripe. The end isnt sealed. Immediate waste if not prepared to preserve.Decent flex when applied

Just like 3m 5200 at a cheaper price
