## Description

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

Review: Waterproof glue for outdoor projects. - VERY HAPPY with product and delivery time ! Did not expect glue for another couple days. Marine glue worked great on plywood project !
Review: This does what it says it will do - 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.

### ⭐ Great product! But terrible handling of the product
*by P***H on May 5, 2023*

3M 5200 may be the best product on the market for sealing boats. If the product doesn’t come undamaged you can’t use it. The product doesn’t come with an applicator tip you can’t use it. What’s wrong with Amazon in their shipping? You shipped me a product which was damaged and unusable AND NO APPLICATOR TIP! wasting my time not only can I not get my project done on time I have to get in the car and drive to the UPS store to return your product. Why did you send it to me a damaged tube in the first place with no tip, is this a joke. Maybe one of your fancy robots did it but if an employee did it, maybe they should be retrained! Thank you. Sincerely, for wasting my time. I only hope that the replacement is in usable condition with an applicator tip.
