Review on 🚤 High-Performance 3M Marine Adhesive Sealant Gallon for Superior Boat Repair and Bonding by Nick Narvasa

I really like this sealant for the outside seams of my RV. It seems to last a long time, has good adhesion, is a nice white color and doesn't yellow visibly (like your 4200 Sealer) although dirt can stick to it (I guess it's inevitable). But the last time I used this smaller tube, it was difficult to extrude a small bead without the help of a caulking gun. I bought another one for a minor touch up, saving money on the size of a caulking gun; but the last time i swore i would never buy this size again because the compressive strength was too big. I haven't opened or used it yet. Maybe there was a problem with the first instance, but I doubt it. I expect to regret buying this size again (because of the compression hassle) when I finally use it.
