I hate the way that gold gas cap looks on my dark monster. I would like to get it anodized black so that way its still lockable and looks better. Where would I get something like this done and how much do you think it would cost? I'm in L.A.
i'm a big fan of powdercoating, but if the part can be anodized, i think it's the better route. (just adding a counterpoint to this thread). although more durable than regular paint, powdercoating does chip easier than anodizing and it also adds (very very very little) weight while anodizing is just oxidizing the aluminum surface with a dye in the tub (no weight added to my knowledge).
that said, for a part to look good anodized, it's gotta be VERY smooth. this is why billet parts look nice anodized and cast parts usually look like kakka. a cast part will have a much more porous surface (result of being released from the mold) which will have to be sanded smooth prior to anodizing for a nice finish.
soooooooooooooooo... in the end powdercoating _may_ be the better option as suggested by mostrack.
