Avoid contact with brake fluid, water, soap, thinners, abrasives, etc... This
plating becomes tougher with age, but is very vulnerable when fresh. Certain fluids
and abrasives, including wax, may remove the gold coating. When your booster needs
wiping off, use a towel with a slight dampness to accomplish this. Spraying a clear
coat on will neutralize the red and green colors in the plating. If in doubt, call
or e-mail me first.
