Lexan is tough stuff.....there is a general rule in materials...the harder (scratch resistant) the material is, the more brittle it is (prone to cracking).
Lexan can bend, you can drill it, cut it, saw it......it wont crack. Its soft and pliable.....and yes, if you do scratch it a little Novus or other type of buffing compound for plastics should work fine......
On the other hand, its also real expensive.....cuz its used as a security tyep of material..ie: instead of glass, cuz you can't break through this stuff...and I believe its technically "bullet proof", but I'm not sure at what thickness..
PS: You can get it cheaply in sheets at mcMaster-carr online.....$27.00 for a large sheet compared to $50 at home depot....
HOwever...I'd much rather work with lexan than deal with the hassles of drilling plexi.....drilling my CP (3/4 MDF and Lexan on top) for 4 players was a PAIN IN THE @SS ENOUGH without having to worry about cracking plexi with each new drilled hole I made..
