I use to have the black rock stars on my old car and I had the same problem. Matte paint seems to have alot more texture to it and I couldn't figure out why these white spots wouldn't go away. Long story short it had to be soap scum I suppose from not properly rinsing or washing in the 105+ heat in TX either way clay bar and then I used the rim cleaner by power ball or whatever the little foam ball that you stick on a drill.. Good luck let me know what happens
Speed.... It's moves us all
