2P-10 is a two-part ten-second adhesive. Just apply the adhesive, then spray the activator and stick it together for a strong, permanent bond. 2P-10 Activator 2oz. is great for small jobs.   2P-10 can be used on any material as long as it is clean and the surface is well prepared. The surface should be clean, with no oil, and slightly etched so the glue can bite more effectively. It should not be used in lieu of a weld (on metal), but it is very effective for tacking, to hold a piece in place.
