Black is tough

[turbomangt]

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.

My buddy's 92 black 525 seems to have no clearcoat, simply run your fingernail on it and a white line appears, it's been like this for years. Why do companies use a light primer on a dark car?

Kings, that's a good question. I think the reason is they can spray ALL the cars with the same primer no matter what color the base coat is. I have seen some higher end cars with the primer coat the same color as the base coat. But you pay for it in the price of the car. to test if a car has clear coat or not, simply take a little of an abrasive polish and in a spot not noticeable rub it with a terri pad, if the color comes off on the pad it iis NOT clear coated.

You know, a scratch in the clear coat also appears white.
