Better Than Caulk

Unlike caulk, GREAT STUFF™ foam insulation expands to fill gaps and cracks.GREAT STUFF™ is also easier to use, dries faster, cures firm and is sandable, paintable and stainable. Not to mention a single 12 oz can of GREAT STUFF™ equals up to 19 tubes of caulk. Caulk is good stuff, but it's not GREAT STUFF™.
