The MetalCloak Control Arms are Zinc Plated with a Gold Chromate Conversion Coating.
If you drive your Jeep in severe salt conditions, like near the ocean or in snow weather zones that use salt on the streets we recommend painting the arms for added sealing protection.
If you are not in a severe salt environment, painting is not needed, the Zinc Plating with a Gold Chromate Conversion Coating is a very durable and very long lasting protection against corrosion. Please watch our video below.
I hope this information is helpful.
