At present I have experimental approach to some of the burl repair, but only preliminary tests have been promising, I have not had a chance to do a full radio at this time, due to a lack of time, however, if you seal the flaked portion of the surface with something like Testor's "Dull coat Lacquer", you can see if you can find art markers that match the burling. Once matched, the damaged area gets spot repaired with a brush (to raise the level of the are where the lacquer chipped out. Wet sand the area, then give one or two coats of sprayed on lacquer.
This is only experimental at this time, I have not had a chance to de-bug the approach. The wet sanding is done with water, and paer grades of 320, 400, 800, and maybe 1000 if available. If you apply a coat of paste wax after sanding with 800, you get an appearance that is original for many radios. If you need the extra gloss, use the 1000 grit, followed by automotive polishing compounds.
If the old lacquer has started to delaminate from the wood, first try brushing the area with high working temp lacquer reducer, and let it dry. This will usually re-adhear lacquer.
I would be inclined to leave it alone if it is not noticable. Only repair the veneer if there are sections that are gone, or if it has delaminated.
: I am now the proud owner of a Crosley 5M3 fiver. The oringial lacquer finish is about one third gone. The original veneer is about 1/16 inch maple but it is covered with a lacquer that somehow includes a fake wood grain that looks like burled butternut. I suspect it cannot be repaired to an acceptable level. I would like to know how the original surface was manufactured (I don't think it is lacquered covered paper because it is so thin) Can it be repaired and how and if not should I re-veneer it or not? Opinons would be greatly appreciated.
