Great Stuff Multipurpose Black Foam Sealant Smart Dispenser - Insulated - 12 Oz

[This review was collected as part of a promotion.] Works as it should. There is a learning curve for application, but once you get the hang of it works well. Definitely use some gloves when using and cover any surrounding area as this will stain. Wish it wasn't just a one time use though.

[This review was collected as part of a promotion.] I've used other brands of foam sealant that were impossible to manage. They expanded so much or not enough. I did a patch test with light valve pressure and one with firm valve pressure so I knew exactly what I was dealing with. It controlled both times beautifully. I used this to fill the gaps on my window A/C unit and it worked like a charm. I then used it to fill a gap in a water line through my pantry in my camper. Ants were getting in and now they are gone! I love the black color versus the dingy yellowing colors of the other sealants. I even used this to patch a hole in my son's skimboard. I used an exacto knife to trim it flush to the surface once dried and it has withheld many uses since. Always use gloves when applying sealants as it can be a messy job until you learn to control the valve and the smart dispenser.
