Customer Reviews for 3M 10 oz. White 5200 Marine Adhesive Polyurethane Sealant

i wish i had read the cure time i was rushing through my project because i didn't want it to harden on me... it takes 48 hr to stop being tacky... i literally could have stopped halfway through and started again the next day.. but my project is a solid as if i welded it...

Great for filling hull cracks prior to paint. Not sandable, so avoid excess.

This adhesive is so strong that buyer better beware that it is PERMANENT. Upon trying to remove a console this was used when applying to plywood, the plywood broke and the section came off with the console.

Make sure what ever you use this on you would rather not take apart again.this is permanent does a great job above and below the water line waterproof absolutely.

Great for all aplications

The best on the market 100% water prof

Excellent sealant great for sealing aquariums and underwater works.

If you are looking for the best adhesive sealant, look no further, this is it. It has adhered metal fascia to a rounded deck edge for going on 22 years without incident. Expensive, yes. Worth it, definitely.

I used it to repair a 36 year old two man plastic boat. Hole was below waterline. I have had to boat out several times since, and NO problems with any leaks at all. Great product, and if the occasion arises, will definitely use it again.

This stuff is awesome, just make sure to seal ALL air out for future use or it will turn hard as a rock.

It works.

This is a very strong and tough structural sealant. Best used on things you don't plan on taking apart.

Used to reseal roof vent on camper. Worked like a charm.

Used to install new they hulls on my boat. Worked perfect.

Very good product.

Good product!

Used this to repair the fiberglass skin on a camper that we bought. It took a few days to set up so it was not sticky, but after a week it was stuck and stayed stuck. Be prepared to wait while it cures before you try to use what ever you are working on.

Buy the smallest size you can find and the fast cure unless you have lots (a week) of time.

Saw a review for this on YouTube channel Project Farm to be used as a construction adhesive. It failed miserably, even after waiting a full week for the 7day cure time. I have one tube left and I will be bringing it back. It had about the same efficacy as Elmer's glue.

The best sealant you get for campers and marine application.

Works great. Sealed leaks in my metal roof. Goes on easy. Does have a couple of days drying time. Looks like it will stay soft and not crack.

Best marine adhesive. Far better price than marine stores!

Great Product!

A must have for Marine applications, glad to see you carry the product. Wish you carried 316 Stainless in hardware

Easy transaction and pickup.
