Well, not exactly. A number of sets used painted chassis over the
years. They didn't have a problem with out-gassing. They were
generally painted before assembly and baked or otherwise cured
afterward. Same principals still apply today. I've had no problem
baking assembled chassis in the 125-150 degree range after removing
things like plastic dials and such. In fact, carbon resistors and
transformers can benefit from a mild baking to remove the moisture
that both readily absorb over time.

Steel wool is also a handy tool in the proper circumstances and
application. Not a good idea to use it on softer metals or surfaces
that can hold little bits for later rusting. Also not a good idea to
use it inside electronics were the droppings can cause arcing. Four
aught steel wool is excellent for polishing hardware and a number of
other uses.

The trick to both is doing it correctly. Neither are inherently bad,
though the application of any tips listed so far can as bad as
anything else, if done improperly.

There is no substitute for experience and moderation. When in doubt,
ask questions. Seek out those with years of experience.
