3M Marine Adhesive Sealant 4200 FC

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!!

This came packed between 2 12volt batteries. Needless to say fedup X handled with care( that they would ruin whatever was inside.) And that they accomplished as well as a professional demo team could! I used a spatula for what I could but there was a lot of waste, I will be buying at home dep. unless Amazon teaches the shipping packer of theirs how to pack, Amazon should have their people put in a shipped or packed by slip to get feedback on an employee that doesn't care about the quality of their work. Other than that the product was Great!

Works as expected

Fast shipping and quality product.

I wish there had been a clear version available. Outside of that I liked the product and the apparent adhesive qualities. The true test will be its sustainability in properly preparing and adhering two resin vases to a granite headstone. Hopefully it lasts for a very long time.

Used for corn of camper. Don’t think I will use anymore for it though . Its a firm latex sealer. Used only on one corner, this would be hard to remove if corner seal needs to be replaced. Most campers have a flexible putty tape. However the Dicor sealer tape i used under it STICKS, it ain’t coming off either. So hopefully no ballooning of the camper siding now. We’ll see next year how it does. Recommend using VERY soap water if you use your fingers to smooth, or a silicone tool sealer tool . Fingers would be easier. I tried both. The sealant is placed OVER the dicor tape, putting sealant inside the metal corner piece and secured back in-place with screws. The sealant will be pushed out the sides , then you smooth it out. This stuff should work great for boats.

Great product!

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