WARNING: This is not a 3M hot melt adhesive. The sticks have an extremely low melting point and when used in 3M Polygun TC the adhesive flows like water. I've been using this Polygun with 3M Holt-Melt for 12 years and have never had this low temp glue. Looks and feels like cheap glue guns molded for Polygun. Everything gets thrown in the trash and reordered by someone who actually sells 3M products.
