3M 7000000623 Marine Adhesive Sealant - 10 oz., White

Super good. Once it’s sticks no turning back.

Strong glue and sealant. I used it for gluing a tile back down. Worked well.

Great product if I had an applicator. As other reviewers have noted, received sealant without applicator nozzle so I am unable to use. I figured maybe seller would have corrected this problem but I figured wrong. Tube is in good shape though. MFG date 01/29/24. "Free" returns means a 70 mi round trip to nearest UPS store.

This product was used to help repair a very old cement statue that sits in a fountain and has a tube running through it to the top of the head to create a nice bubbling and trickling effect. After days or rain, the ground gave way under the heavy fountain and the little girl fell over, breaking the neck. The tube held the head and rest of the body together, but a large amount of cement around the neck crumbled. We applied this as a filler around the head and neck after using a cement adhesive to glue the head back onto the neck and shoulders. In a few days, all was dry, and it rained again--but this sealant held. Being waterproof is a necessity for a fountain statue and cracked fountain bowls.

Excellent marine product.

Product is fine but Amazon didn’t ship the applicator tip!

If you are using this product for marine usage above or below the waterline, well you made a good choice. It is a bit pricey but will pay off in the long run. Way to use and easy cleanup. Follow the instructions for usage, cleanup and storage and you can’t go wrong! Seal em up!

I've been using 3M slow cure on the boats for years it's great stuff but I'm sure this is an Amazon issue it got sent without the dispensing nozzle that screws on to the tube basically making the tube worthless
