Clears
Brightener makes a big difference in clear chromates. 3 different chromates were used here:
far left - bright plated w/heavy blue iridescent chromate
center left - bright plated w/Caswell light iridescent "Blue" clear
center right - unbrightened w/Caswelllight iridescent "Blue" clear
far right - unbrightened w/non iridescent clear
