I'm on attempt #3 to bed my Talley picatinny rail to my Bergara B-14. The first two tries resulted in part of the JB Weld sticking to the action and part of it on the rail. I've sanded the rail and used plenty of Kiwi shoe polish on the action. Could it be a time issue? The first try was a 4 hour set time, and the second was 5 1/2. Anyone let it sit longer? People on YouTube recommend 5 hours, but that isn't working.
