Except you _really_ don’t want to get TiCl4 on your skin (it will react even more vigorously than in air), and it effects the metal finish by making a kind of dark etched area, so it ruins the gun you put it on.

Hey…I  did all those dumb things….Let’s not forget, formaldehyde in paint (rain proof it), all those heavy metal scene paints and aniline dyes(cadmium yellow, malachite green etc), sheet lead that you cut with a jig saw to  make great acanthus leaves on “stone”,  and the ever popular asbestos shorts (short asbestos fibers used like instant paper mache for texture-just add water) .  (what’s a dust mask?)

and all those things I didn’t do…like smoking and drinking …...well not much of anyway….I  did live thru the 60’s and 70’s


Also still alive but maybe not for long…
