I am thinking about removing the mylar on my big guns and looking for some advice on whether to do it and which method. It has a gorgeous playfield without any wear, even in the unmylared areas, but the mylar on it is bubbling severely in spots and is wavy and ripply. I did a little research on pinside and mylar removal on a system 11 can be difficult. Any advice on using a hair dryer or freeze spray method which would be better? If freeze spray method, which one? Thanks

There is one spot that is about 5 inches by a half inch long that is a bubble. Like I said it is also ripply and wavy in other spots.
