Default Repairing chips in lacquer on 'woodie' cabinets

'Woodie' radio cabinets were invariably sprayed with nitro-cellulose lacquer. Sometimes they're too far gone and need careful stripping and re-varnishing by whatever means are favoured, the easiest of which is Danish Oil. I've tended to use that on cabinets on which the grain of the veneer is quite open. On cabinets where the finish was high gloss on closed grain veneers, I've found that 'Tetrosyl Professional Trade Spray Paint Clear Lacquer', which comes in 500ml aerosol cans, is excellent. It can be found on e-bay for about £5.00 a can by entering that word string into google. (Halfords and others do clear acrylic varnish too of course).

However, this thread isn't about the total stripping of cabinets, but to suggest a technique for repairing small chips in lacquer, particularly on high gloss cabinets as found on Grundig 'woodies' and the like. The technique is known as 'drop filling' and is used by musical instrument repairers to repair 'dings' and chips in the lacquer on the soundboards of guitars & mandolins. If you watch this video, you'll see how the technique is used to make invisible repairs. I've used that with success to restore small blemishes on wooden cabinets.

As will be seen, it involves the uses of a single-sided razor blade as a scraper, spaced .002" above the surface of the area of the repair before 'strip sanding', going through progressively finer grits from 400G to 12,000G, then finally polishing. It's not an especially skilled technique, but not worth attempting by anyone who has neither the patience nor inclination to do it. The short video at this link shows how its done on a guitar soundboard. The results achieved speak for themselves:

Hope that might interest someone.
