Time to replace the safety tapes - mylars are still in good shape and are well attached.


I know this might seem overly simplistic, but if the mylars are in good shape, and well attached.... why, oh why, would you want to screw with it at all?
But you have already heard from the experts on which materials to use.

Warm air from a hair dryer helps lift the old double sided tape. If you can keep your fingers on it, it isn't too hot. Roll it with the grit of your finger prints. You will have smooth finger tips inside two hours.
Clean, clean, clean before you try to reinstall new double tape.
When you lay the mylar on top, use a smooth wood dowel end and rub firmly to
warm and remove bubbles and get good adhesion. But be kind to hinge spots.

PITA job, any way you look at it. :-)
