The OP isn't giving enough info for anyone to give a reasoned reply. What model tt? What tonearm? Are the scratches on the arm board, or on the tonearm itself? Etc.
Saying that, I'll guess at what's going on:
You've got an HW-19 JR. These were often shipped with an Audio Quest tonearm.
Plinth scratches? VPI has no one on board to spend the time to come up with innovative, one-off repairs to a finish of an out-of-production tt, or even do a complete refinish. They no longer carry the plinths for this deck. If you had a tt that they had parts for, I'm sure they'd be more than happy to ship you an entire new plinth. This is a problem, however, that could easily be sourced out locally, or even done diy.
Tonearm base scratches? I'll assume you mean the armboard. VPI no longer carries armboards for the HW-19 series. However, again, this is a project that could be easily sourced out locally. Are the scratches actually on the "tonearm base"? If the tonearm is JMW, I'm sure VPI would send you the appropriate part. If not a JMW, VPI does not have access to the many, many tonearms that might have been mounted on the decks.
There reaches a point, especially with outdated products, where a person has to do more legwork than simply calling a manufacturer and dumping the whole mess in their lap. A belt-drive turntable isn't an artificial heart-it's a simple machine on which anyone can learn to do simple repairs. You can 'be discouraged' if you must, but if you reach that point from a few cosmetic scratches, maybe vinyl isn't for you.
Once again, all conjecture-no info.
