When I was a kid I tried to silver spraypaint (a.k.a. Mexican Chrome) a bike frame and it looked fantastic...
.. right up untill I tried to ride the bike for a few hours.. then it turned to kind of a lead color.
So i'd spruce it up every other day or so.. till finally I must have had about 50 coats on it.. you could dimple it with your thumbnail!
Not only did it LOOK like a lead bike frame, but it looked as soft as a lead frame, too!
I'm going to keep my eye out for a lower chrome grill cheap (yea, I know.. keep dreaming!) but i'll probably just end up taking this one to somebody to have it media blasted and rechromed.
