I used signwriting graphic vinyl sheet on my last cover up. I get it from local signmakers a couple of doors down. Last lot I got was glossy black (ImagePerfect 5700 and some Profix), but 3M Di-Noc is good as it will heat and stretch really well for complex shapes. Julian, boss of ths sign place gave me enough to cover a small shed and it only cost me a packet of biccies for his brewtime,I did offer to pay,he declined and still asked if I had enough for the job!,(it was to mask bare carbon on a frame). They had tons of roll-end and scrap pieces and loads of colours and finishes. They have made me bike logos in the past,(I did pay for that!). Worth a quick call/visit to a signmaker near you maybe. Ask nice and it may only cost you a packet of biscuits too!.
