Here is another window that was saved after being vandalized.  Graffiti was scratched into this window, the glass was large and of a unique shape. Replacement would not have been cheap, in fact we could resurface it again 4-5 times for less than it would cost to replace once (hopefully we don’t have to though!)

People often ask if removing scratches from the glass weakens it.  Good question, but no, removing scratches doesn’t weaken the glass.  Actually, having scratches in your glass weakens it, if something hits your glass with force, most likely the area where the scratches are is where it will break.  This is how glass is cut to size, they don’t cut it with a saw like a piece of plywood, they score it and then tap it and the glass breaks along the scored edge.  With this in mind, it’s easy to understand why removing scratches from your glass actually STRENGTHENS it rather than weakens it.
