I have windows on my Sandman (two to be precise) which i'm not big on. Sometime down the track i'm gonna have them covered up but I'm gonna make sure it's done by someone who knows what they're doing. Too many horror stories.

My advice would find someone professional (preferably someone who's done it before, numerous times). I wouldn't be touching it, even if I knew how to do it. Too bloody hard! :lol
