I'm building an illusion which utilizes a 4x8 sheet of plexiglass/lexan/"insert type of plastic here". It's different from the girl thru glass, but shares a common problem. It seems to me that, when the glass makes "the move" over and over, through lots of performances, that it would start to show wear at the top edge, spoiling the illusion. Has anyone here come up with a solution to this? I could build the frame so that it's padded, but even that would act as an abrasive over time. And, with lexan, plexi, or any of the known plastics, there are none that are totally scratch/scuff proof. Thanks for all responses!

Padding with a non-abrasive material will help. I'd imagine that a periodic polishing would keep everything spiffy! Eliminate small surface scratches before they become deep.

The new non-abrasive cloth may be a solution. They make dust cloths with this material. It is called Micro Fiber. Just a suggestion.

Spacers? - Just a thought!

The girl through mirrors that I make is lined with felt. That seems to work. You could always try nylon tape in the side channels. http://www.rockler.com/product.cfm?page=......n%20tape

Perhaps applying spray-on silicone lubricant (sprays on, but dries) where necessary could help?

You're thinking about it backwards.

Earl has it correct.. if you want nothing to scratch.. you have to keep anything from touching it..
Bolt the nylon or guides ONTO the glass.. and keep just a bit of space between the glass and the frame.
