Marv:
     I get my MC from:

JLM Chemical
P.O. Box 15038   (4041 Park Avenue)
St. Louis, MO 63110-0038
(314) 865-5368

MC is currently running about $61.35 for five gallons, they will ship
"common carrier rates" in quantities over five gallons.  Pure MC is a heavy
fluid (about 13 pounds /gallon) so a five gallon can weighs about 70 pounds.
I use a lot of it apparently since I'm on my second five gallons.

     Some words about solvents.  First of all, the varieties of solvents one
can get at the hardware store are usually not sufficiently pure since they
are made principally for paint stripping.  MC is the best degreaser and is
not flammable which is important since composites can build static charges
when you're doing all that sanding.  Acetone is also an acceptable
degreaser/solvent, but it is highly flammable.  MEK is also a degreaser; it
is also highly flammable, is so penetrating it ought only to be handled with
a lot of protection, and it is carcinogenic.  Liquid MEK on the skin is
asking for cancer and it goes through everything (maybe butyl gloves with
cotton inserts would be sufficient).  A drop of MEK in the eye of one of my
troops years ago resulted in the eventual removal of the orbit.  It's really
bad stuff for humans to handle.  I can't see taking all that exposure for
the life of building the airplane.  What a shame it would be to develop
cancer after you've finished.

Cheers, 
Pete
