Using GW grip tape and solvent but grips sticks halfway on does solvent go bad?
Solvent will not go bad for a long time. My experience with what you are experiencing is simply a case of not enough solvent. The inside of the grip needs to be coated with solvent, the grip tape should be drenched, then you need to work fast. In our schools, 99.9% of the time when students get the grip stuck half way on, they didn’t use enough solvent and they didn’t work fast enough.
