Default Repairing catalysed lacquer type finishes

On my Grundig 4070U the corners got a beating. I have finally got hold of some cellulose thinners to attempt to remove the finish on the corners so I can repair the veneers and then re-finish.

The clue is in the 'attempt' - the thinner makes no impact whatsoever on the finish, so I expect it is some form of catalysed lacquer rather than a nitro-cellulose type finish. The thinners didn't even make it tacky to the touch at all.

The finish is a high-gloss finish and where the impacts have occurred it has brittle fracture lines so its obviously quite hard.

Are there any hints and tips on how to repair this sort of finish? What can I use to remove the finish and how can I repair the finish and fill scratches etc. ?

I'd rather remove the finish on the corner with a solvent. Using abrasives is likely to damage the veneer even more than it has been already.

Any guidance gratefully received.

Kevin.
