Just a note... I've restored and wrapped a ton of kits and as beautiful as Glass is, it is, (bar none) the hardest wrap I ever had to work with. My hands were in shreds after working with that stuff. The substrate is just like concrete! If you have to cut it, you'll need a specialized cutting tool so it cuts without leaving a ragged edge. I burned through several Gem blades before I figured out that the crap wouldn't cut with ordinary tools.
Glass wrap looks great, no doubt. I prefer it to regular sparkle wraps, however, it is the biggest pain in the a$$ to work with if you're wrapping drums yourself.
Fore-warned is fore-armed.
