My home has unpainted woodwork throughout and also a lot of paneling.
I've been told that the finish was probably lacquer. Anyway, it is
*extremely* fragile! I can cause it to chip by just raking a
finger-nail across it. Chipping isn't really accurate -- it sort of
crystalizes into something that looks like rosin. I have been covering
these chips with Liquid Gold, which does a good job for a couple of
months, but am looking for a more permanent solution. Removing and
redoing the finish isn't practical, but I thought I might clean the
wood with mineral spirits and then wipe some pure tung oil on the
entire surface and wipe off after about 5 minutes. The tung oil should
soak into the wood where there is no finish and then harden. What do
you think about this solution?
