I'm not nearly as good as the guys who've posted here, but here is what I do and I've had all sorts of problems, but bubbling has not been one.
1. AMTAK Epoxy
2. Heat Part A and then measure it into a syringe
3. Repeat with Part B
4. Mix epoxy on an aluminum pie plate. Mix with even strokes for a full minutes (you'll be surprised at how long this is if you time it)
5. Heat with alcohol lamp under pie plate. Not too much, if it starts smoking and you are freebasing epoxy, that's too much
Then do your wraps, and then hit them with the lamp afterwards. Sometimes depending on the rod I'll reheat the epoxy as I'm wrapping.
