Hey there guys

I have an anodized boat tower that has been cut / modified and re-welded in several places and the bright silver anodized finish has been ground away and the repair pieces are raw aluminum. The question is does anyone know of an spray paint type of product that would closely restore the anodized look.
Ofcourse this is just for the astetics not the corrosion protection that an anodized finish offers.

thanks
Mark
