Has anyone tried to reactivate the glue where the mylar has bubbled on the playfield ? The mylar lifts after years of heat from the std lightbulbs in the inserts. As it lifts, air has to be drawn in from underneath. That air can only come through the small space that is created over the years between the inserts and the surrounding p.f. To me that would mean the lightbulbs also dry and shrink the silicone or woodglue that hold the inserts, enabling air to rise. The mylar glue is dry but since no moisture has ever been there I would think that pricking a small hole in the bubble and carefully heating the area can reactivate the glue, push it flush, let the air escape and let the glue set again. Correct ?
My concern is if the glue activates at a dangerously high temperature, then we are passed the point of no return where either the mylar or the playfield itself has already started taking damage...
Your thoughts and experience here is invaluable... I really need to rid them bubbles....
Thanks
