It clams to be the same color but is the zinc phosphate the right color for the caps or do you have to top coat them with color?And is the zinc the rough texture on the caps?
I'm cleaning my wheels up and need the texture stuff as mine have 3 with a lot of texture but one has just a little and they would be a nightmare to try to clean off.All the caps are different shades also so I need to get them the same color.As always any suggestions are greatly appreciated.
