Quoted from beatmaster:
from that picture, it looks like you have mylar around the pop, i'd be curious to see the lower part of the playfield i'm guessing like the others said you probably have mylar in front of the slingshots.
the ones around the pops doesn't look too bad, i wouldn't be concern about those. a lot of actions around that area, wouldn't remove those, unless you want to clear the playfield.
You guys nailed it, I've got the mylar going on in front of the slingshots as well (wasn't sure what to call them earlier). I have a pic, it's attached, but it's a bit blurry and might be hard to make out (iPhone camera, argh!). But that's good to know. I just assumed game boards were completely mylar coated, and not just select areas. Makes sense from a cost standpoint, I guess.
At any rate, your restoration is looking extremely good. You're making me think I'd really like to do a touch-up on the art, and a full clear coat over the playfield. I'm assuming you're shopping out the clear coat to a local shop? I neither have the equipment nor the experience to do an automotive clear coat myself, but I think I have enough art experience to deal with the touch up as long as I take my time.
Just to be sure, was the Createx mentioned earlier the brand of paint you're using for touch ups?
Thanks and again, awesome looking work! The Space Shuttle restore was fan-tas-tic.
