Lacquer Finish Repair

This is a Klipsch Cornwall speaker cabinet which has water damage from a house plant that sat on top. I would like to do what i can to repair it or at least make it look less damaged. I have reason to believe these were finished at the factory with lacquer. But the problem is this:

"Lacquer" is a family of products with different formulations. For example, I am currently finishing a guitar body using nitrocellulose lacquer which is a different animal from other lacquers. Apparently, there are both water-based and solvent-based lacquers. And there are lacquers that "cure" and lacquers that don't.

Most (but not all) lacquers simply dry. The solvent evaporates leaving a resin behind which eventually dries to hardness. These lacquers can be re-wetted. Finishes that cure cannot be re-wetted.

So now you can see my dilemma. I may be able to spray a thinner onto this area which would dissolve and re-flow the lacquer and possibly repair the damage. But I'm guessing I would need to know the specific formulation of the lacquer on this surface. Maybe a bit of lacquer thinner is all I need here. But maybe not.

Does anyone here have experience and advice for me?
