I doubt it's adhesion problems between the new and old, but between the old sealer and the old..........whatever they want to call it(polyester filler). I suspect they used regular ol' vinyl sealer, then sprayed polyester on top of it.(they called it filler ??) It's pretty much a polyester finish with a couple coats of nitro on top. Lacquer should adhere to polyester OK. The impact is separating the polyester from the vinyl sealer. I've refinished a BUNCH of guitars made by a different company because of similar problems. Those problems weren't just on the necks. I suspect you'll need to strip and re finish to completely cure the problem.
