Definitely faded, according to this pic from IPDB ipdb below

As Nino points out its still repairable though, i've done several backglasses lately that were either faded like this one or had considerable paint loss.

In addition to my Zac Universe thread Nino posted the link on, there is also a resto thread on a Gtb Outer Space b/g i did a few years ago, i'll post a link if i can find it!

EDIT; Here is the Outer Space b/g resto thread, link below..

I have a heap of pictures, before and after of some B/Gs i've done in the last few months, but i'm not sure if i should post them in this thread or not, maybe i'll start a new thread showing them
