Paint colour for backing plates ?

Wait a minute we're trying to paint the galvanized backing plates to look galvanized? LOL and after a few stops won't they look like they're full of brake powder? I ask this because I'm currently right there myself right now and I painted most everything but this part at this point doesn't make any sense to do anything more than clean it the best I can. I mean it's galvanized it's not supposed to rust that's first and foremost and mine isn't. I just cleaned mine up the best I could and I'm rolling right there with just that particular part. I would think the dust would need something to cling to?
