BLACK ANODIZED PROBLEM





2003

I HAVE A SET OF BLACK ANODIZED TRUCK BEDRAILS THAT ARE TURNING PURPLE IN COLOR,WHAT IS CAUSING THIS PROBLEM?

Could be numerous things...poor sealing of the coating would be the #1 suspect. Inadequate coating thickness.... using a dye with poor lightfastness. Its almost impossible to tell without physically testing the rails.

Is there a smut that rubs off when parts are dry? If so cut your anodize time by 15 min your parts may be burning in the anodize tank. This is also common on 2000 series substrates.
