Hi,
Can someone tell me how to clean that spots?
I don't know if is alluminium or iron or steel


Spots

 

Rocker panels are aluminum, with a clear anodized plated finish. Chances are, the only way to remove the "spots", is to strip the anodizing off of them, and then polish the aluminum. The problem is that once the anodizing is removed, the aluminum will continue to stain and spot, requiring regular polishing, to maintain the finish.

 

Thank you for your quick answer.
I will try tomorrow with a specific product for alluminium.

 

 

Thanks for the product suggestion.
I hope I will find here in Italy

 

Found Diamon Brite Truck Box polish on Amazon, Wallyworld and other places.

You could clear coat it once you get the stains removed.
