Was it cast (high performance) vinyl?
I'd think it would stay pretty well, for one-off custom work. A big run, no.
You could cut a mask, and spray on some plastic Krylon, then peel out the mask. Expensive, but if you are in a bind, well you know.
Heck. I'd do it FOR YOU!!....if I could fix MY problem for today.
