[R-390] Front panel paint removal

[Bob Nickels]

> One of the cleverest devices I have ever used was a mist degreaser.

Vapor degreasers used to be the standard method for cleaning oily parts
and they did work great.  A sump of solvent, most often a
chlorofluorocarbon (aka "ozone depleter") or nasty stuff like TCE or
methelyne chloride was heated and the vapor was trapped at the desired
height by a chilled band of pipes around the circumference of the tank.
As the vapor rose, it would be cooled and condensate back into the tank.
However there was always some loss, which was never given much thought
"back in the old days".

The process is still used, but obviously with "safe" materials and good
safety systems to prevent the kind of disaster Ken described.   You can

Most folks just use an aqueous cleaning proces these days, it saves on
legal fees...
