Cheers one and all.
Believe it or not I actually gave it a big dusting a little while before taking these pics, that gives you an indication of how bad it was before!
Thanks for that advice though, I may just do that.
On getting the two sections of the ship to fit, there was actually a horrible accident when putting the two bits together again ( I think I had them separated for some reason)...anyway I had had a lot to drink and I used too much force and the front section went up under the back a little and snapped one of the antennae- you'll notice it's a little messy on one of them where I glued it back
Also a flatmate broke one of the two antennae on the back off and didn't say anything about it or retrieve the part- I had to make a crude replacement out of a toothpick
