Quoted from videobrain:Ok, thanks for the advice, I'm starting to feel a bit better about it now. I'll order the glue and it should be here by the time I get the mylar glue off the playfield. I will look into the spot clearcoating as that would definitely be preferable to putting down more mylar.
Replacment mylar is not as bad in my opinion, plus you really only need to cover the area you are touching up, but if you feel comfortable spot clearcoating I say go for it.
