#8. "RE: Glass LCD Cover to replace Nikon Plastic - Available?" In response to In response to 0

It's not quite what you asked, but Nikon sells replacements for about $17 US. That's not cheap, but if you figure they last 4 months or so, it's also not expensive just to replace when they get scratched.
I went the route years ago of leaving it in the box, and all my LCD's still look pristine, despite fairly heavy use. The glass is tough. Your mileage may vary of course.
