eastwood has a product that is 2 stage, the first thing you do is spray a gloss black base coat on what it is you want chrome, then the 2nd stage is the chrome product, you spray light coats over the gloss black and it turns the gloss black to chrome, its badass. they did the roof of a caddy for billy gibbons from zztop on rides with it, the :q:q:q:qing roof turned chrome right in front of them as they sprayed it, it was sick. chrome calipers would look sweet.
Yeah I wonder about heat capabilities too. Now chrome calipers that blued would look really cool!
