I took the back off my lovely MX, to find out when it was assembled
(Oct. "80) and noticed a lot of black deposits on the light-seal
ridges of the back, top and bottom.
Tbinking that was deteriorated foam seal stuff, I got out the
denatured (isopropyl) alcohol and a bunch of swabs.
Well, it dissolves whatever-it-is well, but it keeps coming off, like
tar!
I'm not down to the base metal of the back, but thought I'd stop and
ask what mild solvent is recommended.
This stuff acted like acetone or MEK! I checked the label three times,
to be sure!
The rest of the body is really perfect, but on the back there's some
black stuff coming off, like I was dissolving paint!
What say ye?

I've never replaced mirror box seals, but seals on the back are pretty
easy to do.
I got some foam from this fellow on eekbay

The little bamboo tool is good for cleaning out the old gunk, with a
little alcohol help (naturally). The new foam just packs into the
grooves, or has a self-adhesive backing for the door areas. Saved the
lives of two Fuji 645s and a Mamiya TLR
