My biggest peeve is watches and bracelets.
After a month of my cab being new, I found a nice deep scratch on the CP plexi near player 2. I then realized that my brother in law was wearing a heavy duty metal watch that grooved into the plexi. Then fast forward to my goth nephew with his spiky stud bracelet, made a nice mess of the CP. I found that I could fix minor scratches with a butane torch, but I think I am going to have to replace the plexi at some point. Anyone use glass or something more durable?
I actually used something less durable (or rather less scratch resistant) - Lexan polycarbonate.
It will scratch easier than Plexiglas, but it is so much easier to cut and drill.
If I get scratches, I'm planning on using micromesh to buff them out.
If you don't know what micromesh is, try a quick Google search - it is amazing stuff.
I use it to remove scratches and polish plastic all the time, and it will bring it to a glossy finish very quickly and easily.
