I was just deciding whether to do this as well on BOP.
Quoted from Cheddar:Not really unless you are lucky and got one of the early clear coated ones. too many times the insert art comes right off on BoP
As far as the insert art coming off, wouldnt that just be a case of getting replacement inserts like available on Ebay (and vendors)? ebay.com link: Williams Bride Of Pinbot Pinball Machine Insert Decals LICENSED
If it is that simple, and your mylar is wasted, I would seriously think about the freeze spray option. There are also new full board mylar sheets available on ebay (and some of the vendors) to put back on if you want to go that route. I did the same on Pinbot a while back (took off the mylar) and a beat playfield went to being pretty damn good!
