Todd, I have not had to do this, but I belive you might want to look into butyl cellosolve. good luck |

Do you know that you are working on nitro lacquer? Doesn't sound like it. You can sometimes glue down a delaminating finish with CA. I doubt that butyl cellosolve will help if you can't get burn in. |

Butyl Cellosolve is the answer. Spray some on with an airbrush and overcover the area to be fixed, spray your nitro on the fix, and overcover with another coat of Cellosolve. You can mostly fix delams by running some Cellosolve into the crack. |

Welcome Todd. Got the tips from Charlie Hoffman. If you overspray by a wider margin than the local "fix" area, it seems to meld better and the shrinkage of the "fix" area is not so evident compared to the area next to it as a larger area than the "fix" is re-softened. |

Flooding with butyl cellosolve can soften your finish for years. I avoid it if possible. But if you are getting the finish to dissolve completely in lacquer thinner I'm not understanding why you say you have a problem with burn-in to the topcoat. Ask impatient owners if they prefer fast or good. |

Howard, overspraying with an airbrush is not flooding the area. |

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. |
