Brett, no offense, but let me get this straight...you guys are using TCE
to thin contact cement or 3M77 to cover an indoor ship with film?...MEK is
about as bad as one should be using.
Back up about 10' and think about that. TCE probably one of the more
corrosive solvent/degreasers on the planet. It's used as a degreaser in
contained vats with total enclosed ventilation...like dipping snowmobile frames
in before priming. The folks in the work areas need protective clothing and
respirators. Any skin contact and your skin is immediately
degreased...not a good thing unless you don't want to leave any fingerprints. But, it
will clean your tools though!
It has a vapor pressure that allows it to form a "vapor cloud" over its
surface. Inside of a jar say that is half full, the vapor cloud is probably
1/2"-1"...be careful! The degreaser vats I am familiar with were 5' deep
and only had 2' of TCE in them...it needed about 2' of freeboard above the
wet bath to contain the vapor cloud...and cover doors with no electric
openers on them...all mechanical too...no oil. Explosion proof lighting in the
work area. A hot light bulb could ignite the fumes.
The folks in the work areas need protective clothing and respirators. Any
skin contact and your skin is immediately degreased...not a good thing.
But, it will clean your tools though!
Having used it in military and commercial applications it's not something
you want to have in any quantity in your shop. Plus, you just can't dump
the excess down your toilet either. My advice is find something else.

Also worth mentioning is that I've started wearing a respirator while
working with TCE when covering wings and stabs, due to all the cancer warnings.

mylar)
In Bloomington, Indiana, trichloroethylene, technical grade, is available
in 4 liter sized containers at the IU chemistry store for $17.30. This is
less expensive than Bestine Solvent but more expensive than Coleman fuel.
Sorry John, the quest for the ultimate indoor plane does not persuade me
to buy some and to distribute smaller quatities to other indoor fliers.
