I was looking for a seam sealer for my custom Jeep and found this product. It works as advertised, stays flexible when cured and is able to be applied with a normal caulk gun. Whatever project you’re working on, try to use the whole tube, otherwise it will cure on you inside the tube and will be rendered useless.

I bought the first one that came without an applicator tip that was supposed to be supplied and necessary to properly use the product. Also, the metal tube was damaged on the first and second one I ordered. If air comes into contact with the contents, it will harden and be useless. I took a chance on the least damaged tube and it was good. I returned the other tube. A regular painters caulk gun works fine. This caulk works great.

It’s 3m brand. Not much needs to be said. Super easy flowing, urethan based sealer. Works in any normal caulking gun. Easy to use and cleanup. Levels extremely well. Have used extensively, love it. Can paint in short order with excellent results.

Excellent product- easy to apply and did have the nozzle included. This product was recommended for use on a 1970 Plymouth to replace the 52 year old factory seam sealer on the floor pan. Used three flux brushes taped together to replicate the look of the original sealer.

Worked great, got about 25′ of a heavy bead per tube. Bought 3 tubes, only came with one tip. Plan on using a full tube at a time, so I can clean out and reuse the tip. But if you are planning on 1:1 tip/tube, may not get it.

After sealed and painted no leaks at all and I like the rubbery finish once it’s cured.

Excellent value! One tube revealed the entire firewall and cowl of my 70 C10.Went on easy using a pneumatic caulk gun and 2 trimmed down acid brushes taped together. Even in 50* weather. Only time will tell how well it holds up, but for now I’m satisfied.
