Well, as far as finish blemishes and that sort of thing, I don't worry too much about that. I do little to correct anything like that as I am a pretty lousy collector.
Yes, I do know how to do drop-fills, feathers, worming fills, etc., but most of mine are players and it doesn't bother me too much. I got lucky with the body on the TA-70, and with only minor scuffing I used fine finish compound, then swirl remover which cured most of it.
The hardware is a different story. That usually stands out a good bit, and I don't like the feel of pitted or corroded hardware.
There are many things I use depending on the situation. I use polishing compounds ranging from lightly abrasive swirl remover to very coarse reducing compound. Sometimes I use red (medium) or white (fine) jeweler's rouge with a small cotton wheel on the dremel. Other times for very slight problems on chrome hardware I use Semichrome, Neverdull, or other products I would have also used on my scoot in it's day.
The tailpiece on the TA-70 was badly corroded and pitted across the center top, so it was necessary to remove all the chrome and copper base plating and actually polish the steel underneath. Gold hardware is a bit touchy, and I use only very light abrasive compounds on it if at all as the plating is almost always extremely thin. I have had good luck with Tarn-X and other liquids used for restoring silver.
