How was the joint originally prepared? I'm always concerened abouyt contamination and like Boeing, I don't allow lubricants into my bonding shop. This is particularly true of silicone. But what adhesive was used? There are a number of bonding adhesives that are much better than the Jeffco (if that's what you used). Also sanding and cleaning is critical just prior to bonding. I know they say to use industrial grade solvent for cleaning but that has about 3% impurities as I remember. Reagent grade would be better and a lab towel like a Kimwipe is better than paper towels. Good luck on the repair! Dan Newland
