Here is a BMW that came in loaded with swirl marks from who knows where. After the basic process of washing and claying, I used my deep cleaner to get the paint really ready for the swirl removing step. Problems occur when you take the buffer to the finish and still have blemishes and hidden mirco contaminants in the finish. After the paint cleaner I used my DeWalt 443 heavy duty Dual action buffer. The motor is much heavier than the PC and can cut through swirls no problem when using the right Pad/product combination. For this I used Ardex Seal B, an outstanding product specifically for black cars. Finished up with a hand polish and sealant for outstanding results.
