From everyone's experience, which color brush is the best general purpose scrub brush for use ON TIRES with a DA polisher? After watching Mike Phillips and reading threads from the forum, I'm leaning toward the aqua brush (even though the grey brush would probably spin better). I feel like the grey would be too soft, and the white and black too harsh. Anyone have experience with using these brushes on tires with a DA polisher and can share their experiences?
