3M Marine Adhesive Sealant Fast Cure 4200 (06560) – Semi-Permanent Flexible Adhesive Sealant for Boats and RVs, White, Flexible Bonds, Underwater-Safe, 295 mL Cartridge

Had a slight leak in the caulking of our “new to us” camper so we removed the caulking and used this #M Marine Sealent. Cure time was fairly fast, just as advertised. We were expecting major storms the next several days and after 6 straight days of hard rain we were pleased there was no leaking. The application was easy. I recommend cutting the tip at an angle to get a small beading. It did dry with slight coloration. It is not a white/white. I felt the cost was a bit much, but it’s the first time I’ve bought sealant of this nature. That said…. The price I spent on this single tube- and the excellent job it did at stopping the leak was priceless! Will buy again when/ if the need arises in any other locations on the camper. So in that sense, GREAT value for our money!!

Great product!

I have used 3m products for years. Always dependable. Missing nozzles do occur. They sometimes fall off during handling. These tubes don't come wrapped. It happens. I have had it happen myself in my work shop supply cabinet. I once wrote 3m and and was immediately sent a replacement. They are a good company. I trust 3m. The $19 for a 1/10 gal. tube is a good price. bob

Works well for underwater projects fast cure time. Little messy to work with. Recommend gloves.

Any 3M product I've use including this is great. Amazons pricing and availability not so much. Large price swings every few days / weeks and same day, next day, 2 day and next week options come up randomly. I'm sure as always they have an explanation as to why that the lawyers have written. Not to mention the tubes that came in envelopes were dented beyond use and a missing applicator tip on one. But when delivered dent free for 22 bucks its great.

4200 is some great stuff. Nice because it's not permanent but still seals great. The bottom of the 10oz tube has a metal opener on it. Basically, it looks like the top of a grease gun. They do this to provide a better seal on the bottom of the tube so the product doesn't get ruined while sitting. Remove the tab and the bottom has a plunger for a standard caulking gun application. I wanted to put this here because I was confused by the seal, so hope it will help others.

Buy again

It is looks good but I did not use yet

Prodotto valido anche per L'utilizzo sott'acqua.

Great product ! Easy to apply. Used it to repair a fibreglass trailer. Results were better than expected. Easily sanded off the excess adhesive.

Buenisimo y el precio magnífico

Used this to seal the bottom of my leaky aluminium boat. Amazing adhesive that sticks to aluminium and does not wash off. Used it on another boat over 5 years ago and still water tight.

L'ho utilizzato per incollare le valvole di scarico e i porta gomma del wc nautico. Ottimo.
