Why would you need your door blended? Is there rust on it as well? You get spray cans of metallic paint. That rust treatment stuff is good that Helz suggested for the really small areas where sanding down etc would be overkill.
I have no bladdy idea. Like I said everyone is telling me something different..its gettin quite frustrating. i'm gona have a look for that rust treatment stuff. I was told that because its metalic, it means its harder to get it to match and blend in etc....I really dont know. I think im gona go with the buy a wing idea.
