GSR goes ITS, so i do what with my glass sunroof?

Sometimes the roof is curved enough in both directions that the sheet metal needs shaping. An English wheel does the trick.

English wheel, oversized by and inch, and riveted into place, with a 'hide it in plain sight' paintjob i think is the most budget consious collaboration of all the suggestions thus far. My car is black, so a black panel will work quite nicely, and yeah, it's a race car, so a few rivets and some adhesive are going to work out just fine i think.
thanks for all the quick and useful responses! this is a great forum.
