I recently found a 'spray gun' part no 17b manufactured by this company. It's basically a airbrush you run off a spare tire according to the box.

I have a GM MFG Co Inc tool that looks like a yankee screwdriver with a suction cup at the end. Have no idea as to what it is.
Can you send a picture to email@example.com? I'll post it. Thanks!
