Clueless In Sandland
I agree with Kev, Herb. Or, do the fins first with a "chrome" colour (looks more like aluminium anyway) then mask them up and shoot the black....if you are pc the whole cover except for the fins,i think you would be fine,but the clear will keep the fin's looking nice forever.
My valve covers are aluminium but I shot them completely with chrome first, then shot the mirror black in between the fins...
