Absulutely. You dont even have to take the cover off. You can remove the relay from the firewall, tape off the bottom part and paint it a nice black. You could even paint the bracket with a nice rustoleum silver or grey with a brush. Not perfect but would probably look a lot nicer. Its also possible that your relay is already a replacement part, so you might be better off just replacing it with a new part. Prices vary wildly on these so check ebay, or rockauto, or wherever, for a good deal.Is the cover something I can paint??
