I've got an '83 Martin in with loose binding at the waist. It was loose at the lower bout, I used thick viscosity superglue (Special T from Lee Valley Tools) with good results.
There is a lot of outward tension and it will not stay in place at the waist without some sort of clamp (tape).
I understand stewmac's weld-on cement eats finish, and I am very used to super glue. Any suggestions?
