Great product
Worked great for my boat, definitely worth the price to know it’s sealed correctly.

Great sealant - used to reseal around my pool skimmer and also some leaking waders
Good permanent sealant - takes a day or so to harden but great stuff

Missing the application tips
Both tubes arrived without the tips which are supposed to be attached to the tubes.

Good adhesion and feels strong.
This Marine Adhesive Sealant has good adhesion and feels strong. So far did not fell apart under water.

Nozzles not included
I would have been a lot happier if the nozzles had come with the caulk tubes.

Amazing product.
This product was recommended to me for use as a glue for brackets on the roof of a van that would hold a solar panel. This stuff is GREAT! A little messy to use but dries to the touch within a few hours and was completely cured within the timeframe stated on the label. It has not degraded at all on the roof of the RV which is constantly in harsh sun and rain and NOT garaged. I would not hesitate at all to use this as a glue for almost any application where a secure bond is required. You will definitely need to allow it the proper time to cure prior to use. It's costly but well worth the expense.

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.
