Valvecover Modification
 

So i have a powdercoated valve cover that i bought and i like it....but now i have an extra valve cover for my car that i want to make nice....i know it is very popular here to just paint them yourselves but i have a buddy that can anodize it for me for free the next time he does some of his paintball ****....i know that not all things that can be anodized can be powdercoated but since a valve cover can be powdercoated can i anodize it....i'm wondering if anyone would know any reason why i wouldnt be able to anodize it
thanks
