If you have a place on any playfield that is worn, has dips etc. mylar will
not stick, or curls at the ends after played awhile. What you can do to
remedy this is to use AMRON. It is a clear coat. It also uses a
hardener. The good thing about this stuff is it will not yellow, and
conforms to any playfield condition. You can get it at any auto paint
store. It is expensive. Ask for instructions on mixing, and try to spray on,
but you can use a brush.
