Foil can make an acceptable "chrome" on long, straight things like side spears and window surrounds, but trying to "chrome" something like a bumper is going to be a problem, because foil won't really go around compound curves very well. You'll inevitably get wrinkles. Like the guys say, if you want a real "chrome" look, the only way to get it is to have the part plated. There is really no paint available that looks like chrome plating. Alclad is probably the closest, but requires an airbrush and also a fair amount of skill to apply. And even then, it looks more like polished aluminum than "chrome," IMO.
