I just purchased a 08 GL450. The dealer told me the Rear Moon Roof supposed to have a crackled/frosted look. I think the purpose of having moon roof is to have a clear view. Anyone can tell how there's look?
I have a 07 GL450 and the rear most portion of the roof is starting to look stained. I had a shop look at it and was told that the roof of made of a carbon composite for weight reduction and it starts to simply break down after a while. It looks like glass but it is not.
It's made of reglar' old plexiglass, same as aircraft canopies. It will degrade under constant UV exposure. Don't use abrasive cleaners on it as this will accellerate the breakdown. Contrary to the dealer's soothsaying, it is supposed to be clear, not crackled, crazed or dented, wavy or whatever bullshit the flavor of the week is.
