Yeah, Alclad chrome is a good product- but, how often do you really need a good, shiney chrome finish in automotive modeling? When was the last time you looked at the engine of a car, and seen
anything that looked like chrome? Heat shielding, maybe? Well, there's nothing better than metal foil so simulate metal foil- try to paint it and you're likely to be disapointed. Exhausts? Not if the engine has ever been fired up. Brakes? Not when their constantly squeezed by pads- even when new they have a machined surface, not polished.
Everything metallic here that isn't actually metal (dampers, braded cable, and metal foil) is painted with Tamiya acrylics- even the exhausts (and to be completely accurate, the dampers actually would be more correct painted light grey). For non chrome colors, I can't say that Alclad is superior to MM Metalizers, and plain old acrylics can look terrific. Honestly, for me one of the most importaint things in getting good looking metallic components is having good flexibility of color- and this is more than plain aluminum vs polished aluminum. It's nice to be able to darken a metallic just by adding a touch or two of black, to discolor it by adding a bit of orange or blue, to represent an alloy part by adding gold or dark grey or red (note the drive shafts), etc, etc. Not something you can do with Alclad or Metalizer. Alclad is really made for model airplane makers, who want a good metallic finish to simulate unpainted aluminum wings and fuselages. Unless you're building a Delorean, there's not usually much call in automotive modeling for a finish like that.
