This is the Great Planes Pro CA activator with a pump. Compatible with most foams.
For thick and medium CA that doesn't cure as fast as the instant. All you have to do is apply the CA then spray the Activator on the CA and it cures almost instantly. Another way 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 and pump once or twice and it's done.
Includes: One 2oz bottle of Activator
