Pro CA Foam Safe Activator Refill 8 oz

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.
