This is the Tower Hobbies BUILD-IT Activator refill (without pump). This is great for thick and medium CA that doesn"t cure as fast as the instant. FEATURES: Works on many foams and plastics, always test on a scrap piece of material you are using for compatibility. All you have to do is apply the CA, then spray the Activator on the CA and it cures almost instantly. Another way to apply this is to first apply the activator to a piece of balsa you want to join to another piece, then add CA to the other piece. When you put them together, you have an instant glue joint. The pump makes life that much easier, just hold the bottle 4-6" away from area you are spraying & pump once or twice and it"s done. INCLUDES: One 8oz (227g) Refill Bottle of Activator REQUIRES: Pump Bottle (TOWR3804) COMMENTS: CAUTION, This may attack some foams and plastics. Always spray on a test spot first, and ALWAYS wear safety glasses. KEEP OUT OF REACH OF CHILDREN. tjt 12/30/99 ir/jl updt jxs 12/08/04
