re-anodizing
I have some old aluminium parts that are already anodized in green.
I want to re-anodize them and change the color to black.
Do I need to reemove the old anodizing.
If so, I'd like to avoid sanding because I dont want to change the dimmension of this parts. What chemnicals can I use to achive this? Do you sell a product for this?
Thank you very much for the help
Adrian
