I am restoring a Gorf cocktail. The glass is scratched up, and the artwork under the glass is badly flaked/bubbled, and I plan to replace both. I ordered new glass and a repro underlay.
My first question is, what is the best technique for adhering the new underlay?
I searched this forum and decided to use 3M Super 77 spray adhesive, but I have searched Google and Youtube and can't find any advice on the best way to do the job. My plan is to spray the entire top of the underlay (graphic-side-up) with adhesive, let it tack-up for a couple minutes, then carefully place it onto the underside of the glass. I was going to use my old glass as a clamp and leave it on there for a day.
My next question is, does the old, original glass have any value, or should I trash it?
Much appreciation for any advice.
