Yeah, maboot, I know it was not exactly what was asked about - rattle can paint - but I got the sense through reading that several were perhaps looking for that kind of look and finish - the real shiny reflective look.
We've got hundreds of these same similar threads... and the answer never gets any different. If you want that look, you're gonna have to pay for it or get it plated... ain't no such option with spray cans. Hell... even regular paint that you spray with a paint gun or airbrush is usually better than spray can paint, which tends to be overly thinned and not durable at all.
And since many check out these threads... looking for a good answer and options for a good finish, I thought I'd offer what I'd been shown and then people who felt it was what they were looking for, and not so much as a answer to the original question, can go check it out.
It is painted.
