Review on 🔘 310 mL Cartridge of 3M Black Urethane Seam Sealer, Model 08367 by Epickson Palma

I was about to return the product when I read the instructions on the back of the box that recommended using a special, expensive 3M dispenser. Luckily I went back and read another reviewer's note that this cartridge loads in any standard caulking gun dispenser and works great, which is 100% true! There is a tear seal on the back of the container (to extend shelf life). Removing the rear seal reveals a plastic plunger (very similar to that found in cartridges) which is perfect for caulking guns. After loading, pierce the film at the end of the nozzle, mount the nozzle, and if necessary, cut the nozzle for wider application lines. Another tip: After removing the back seal and piercing the end of the nozzle, the product residue dries; Try sealing the entire cartridge in a vacuum bag. I have had success with this with other higher quality and more expensive adhesives and sealants and have found that it extends shelf life almost as if it had never been opened.
