It works
I used this to seal the roof and rear hatch area of my van. This sealant is world class

Works as expected
I ordered it in tan as my boat is a creamish color close to wood brown. The โtanโ is more of a red clay color. But not the end of the world. Still great stuff to use

Like a coat of rubber over the top of whatever
I used this to seal leaking rivets and screws/nuts in my Jon boat. It's tacky as all get out, and if you're not careful it'll end up all over you. But boy does it work great. Seals up nice and tight.

Delivered without plastic nozzle, unusable
I have used 3m 5200 caulk for years, and the quality is excellent. However without the plastic nozzle, I cannot use the product.

Always the best for below waterline.
Allow for recommended cure times! Super strong and durable when cured. Not cheap but top product for adhesive/sealant.

WOW! Super Strong! Fixed my issue
Had a pool leak in an inground pool 18x36 around the fiberglass stairs. Was afraid to pull the gasket as my liner is 5 years old. If the liner tore during this repair, I would need a new liner at 3500-6000 bucks. So I pulled down the water to bottom of stairs, taped off around the stairs, applied #M, waited 48 hours and refilled pool and no leaks. I would warn you that once this is applied, it isn't coming off, AT ALL. Great product
