Roof is a bit of a let down.... Help please :)

Afternoon all.

I'm getting my GTi back to it's shiny glory. The only area that let it down at the moment it the roof.  It's a bit faded.  I am under the impression that the car has had a quick respray job at some point but the roof was left out...

There are a few scratches and there is what looks like a blister on the sunroof panel.  Is there anything I can do to repair the paint even a little bit?

I can put in the hours and elbow grease washing, polishing and waxing but I'm new to detailing when it comes to this. 

Input would be greatly appreciated.

Cheers,

Nick

Have you a DA? If there's a blister you might not be able to do much about it apart from paint. Get some pictures up so we can see it.

I think the blister might be there for good but I will take a couple of pics in the morning.  Don't have DA but it's on the list.
