That sure is a fantastic job...damn...where do you get that mylar from???And is it hard to lay it down with no bubbles...any tricks/advice??
I have done a couple of mylar jobs now (full playfield) and I found the best method is similar to that of installing decals dry...
Basically peel off an inch or so, cut the backing paper off, then line it up and with a soft cloth work it backwards and forwards towards the rest of the sheet. Then lift it up from the undersideand peel off another two or so inches and let the rest of the sheet sit on top of it (like a C). Then slowly and squarely with one hand gently slide the backing paper off as you continue the rubbing from one side of it to the other (hope this makes sense).. Thats the method which works for me!
