I recently picked up an older (early 70s I think) Sigla clear windshield that was a take out at the dealer. It's in excellent shape (no pitting whatsoever) but does have a few scratches that are neither deep nor casual.

I've been told about a product called Rare Earth by Sommaca that will remove these.

anyone ever done this? technique? equipment? other products? also heard of using toothpaste.
