Mending a long crack in a cheek ear in a sidekick. Was careful to mix 50/50 of the Acraglass ingredients (no dye added), and mixed for 4 minutes. The mend is holding, but the excess that squeezed out when I wrapped it with surgical tubing is soft. This makes me wonder if whats in the crack is soft as well. I will still be using the superglue technique for the rest of the inlettjng. Do I have a problem, or need longer time to cure?
