www.pamfast.com/index.php/products/hotmelt/ an old friend called me today raving about how it bonded a metal strip to concrete in 5 min. no more liquid nails or that other stuff that takes between 2-3 hours to bond metal or tack strips to brittle concrete...it heats up very quick and the gluesticks have something in them that creates a very quick bond. any one here have experience with it? i'm thinking about buying one tomorrow
