## Description

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

Review: Tried and true adhesive sealant for marine use or anywhere you need a permanent mounting - Folks, if you have something that needs to be waterproof and almost permanently attached, this is the stuff! I worked for years in the boat business, and this is a "can't live without it" kind of product. It sets up and cures underwater and is immediately waterproof. The adhesiveness of this product can't be over-stated; don't stick it if you plan to move the item later. I've patched seats. convertible tops, and mounted thru-hull fittings WHILE IN THE WATER. It can be removed but it won't be easy. No, its not cheap but it does exactly what it says, and the peace of mind is well worth the price.
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 !

### ⭐ 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.
