Hey Red!
I can't take credit - that is the email cut & pasted - I understand about 1/2 of it!
You want to try talking to this dude... Backglass stuffed? "Just screen it yourself - it's really simple".
Color match touchups on glass? "Yeah easy, you just dilute it with clear - blah, blah, blah...." (He's NOT into pinball at all BTW)
Seriously, any technical stuff about painting or printing - this guy is a walking encyclopedia!
Obviously - I am happy to pass on any questions you or anybody else has?
