I just finished mine last week in gold. Had to get it from eBay vendor "hubcaps plus," the G2 brand.
You should know that there is a limited shelf life on this stuff; it is a 2-part system but will begin to set up on its own after awhile. Vendor sent me a nice, fresh kit.
It doesn't seem like it but you get enough paint to do two or three cars. If I had to do it all again, I'd jack up my beater and paint the calipers on there, too, just to cut out the waste.
Most people choose to split the paint and do one side of the car at a time. If you go this route, remember, you can clean the brush with the brake cleaner. Works great!
