God f**king damnit this just keeps getting better and better.
I would just hit it with some touch up paint, but that's me. Only thing we can do is send the photos to the supplier and ask for it to be returned and a new one shipped. I mean that's really the only way I can think of it getting fixed.
With the brackets two are not required, one is fine. I don't even understand how you could use two of those brackets given that the fittings on the top mean you can only use the supplied bracket on the bottom of it.
Personally I will be mounting mine in the drivers side gaurd and therefore will most likely have to make custom small brackets regardless since it will be sitting in a position where the given bracket will probably be no use.
