OK... it's done:
I placed the glass on pad, on the kitchen table.
I lightly sprayed mist of Purple Power Cleaner, over the glass.
I placed approx 1/8" clear tape on 2 edges of a brand new, single sided razor blade.
I did approx 10" swath at a time across the narrow side of glass. I could hear the texture of the clear coating, as I passed across the glass, until I couldn't. It's SMOOTH!!!
It looks crystal clear, however, there are some very fine line scratches in the glass. I used 1 new blade for whole job. I'm thinking the taped edges, probably wore thru. I'm actually very surprised I have these fine scratches, as I've used razor blades on other glass before.
Overall, I'm much happier with the clear coated over spray off, however, the slight scratching is troubling.
I'd probably try a lacquer thinner on microfiber cloth or car clay, if I ever come across this issue again.
I pass my experience on to you... Live and Learn
