I'm a cable guy and a few months ago I went to a customers home and they had tons of stuff in the garage. Apparently it was all leftovers from a big family estate sale due to deaths in the family......I digress! They said I could take whatever I wanted, and after glancing thought everything I saw a Commodore 64 box! It could have been anything inside but I didn't look because I didn't want to be rude. Once I got home I opened the box and to my amazement it was a BRAND NEW Commodore still in sealed plastics!
That "Test Spray Here" is a rather bad idea if you think about it.
If they don't have a separate rack for not for sale spray bottles solely for testing, imagine buying a spray can and finding out that someone half emptied it while testing.
Don't know if anyone else has suggested it but some places that sell paint for the autobody repair industry can mix custom colours and put them in a regular spray can. They can even add flattening agents to get the right amount of sheen. You could try taking in the unpainted plastic parts and see if you can get a match. I'd try it on a spare piece of scrap plastic first to make sure the solvents don't melt the plastic. I actually don't mind the two tone that you ended up with but if you wanted the original colour, it's an option.
Mohs scale of hardness, you will always scratch the plastic a little with your screwdriver, I suggest using a hard plastic guitar pick, they don't last as long, but work just as well, with no fear of scratching
+1 for Bender! Everything can be solved by bending! In fact, I'm gonna make my own Apple II+ with blackjack and hookers! Ah.. screw the Apple II+ and blackjack! ^_^
My dad thought the shot at 2:56 was pretty funny, since he works with some sort of video filming and editing, so he immediately thought about setting up the camera just to film yourself dropping some stuff in the garbage
