I brought home a really, really nice but slightly grubby SW last week and I just read through this entire thread. Wow. Great mod/restore ideas, and gorgeous games.
My SW is getting bulletproofed to go on location -- it's not going to a bar or anything, it will be treated with respect. That said, it seems like there are tons of breakable things on the playfield, everything from those pesky yellow targets to plastics (plastics seem to hold up switches and other plastics a lot in this game instead of metal hardware, ugh).
One thing I just can't track down is a plastic protector set. Anyone know who originally made those or a way to source them? I'd love to protect the Falcon plastic instead of replacing it all the time!
My positive contribution to the thread:
This site has some much-needed SW plastics. I just received a set and they are of good quality (not perfect color matches, but good) and will work fine: http://www.pinballuniverse.com/starwarsparts.htm
On the opposite side, Marco's decals are unbelievably bad, avoid: http://www.marcospecialties.com/pinball-parts/820-6090-00
