My recently-acquired Rolleiflex has an 80-year-old first-surface mirror that needs to be resilvered. I just spoke with a local business that does glassless mirrors that mimic the properties of a first-surface mirror, but their products are too thick for my application. The owner agreed to provide me with some sheets of mylar so I could experiment with applying it to the original glass. He suggested an adhesive similar to what might be used for window tint. From what I can find, most tint is self-adhesive, so my question is: what sort of spray adhesive would mimic the type used in tint so that I can get a flat surface on the mirror? I'm told the mylar will take a squeegee, so I can use that to press out any excess.
