Nice write up, I did something similar when I saw bluebatmobiles overlay last fall.
I bought on ebay:
eBay Motors: FLAT BLACK VINYL Roll Sheet Kit Adhesive Sticker Decal (item 180210927155 end time Mar-27-08 02:58:08 PDT) about 4 feet and i cut as i go with the HFP lip still on the car. I do have some wrinkles but at that time it was cold out and hard to work on and didn't take my time. I'll redo it soon.
