The Signs of a Bad Paint Job. Auto paint job flaws, such as over spray or poor color choice, are quite obvious. However, many signs of a bad pain job are subtle and difficult to identify. It might be easy to miss small streaks, runs, or poor edge work when looking at an entire surface.
Wash your car with car soap and rinse it with cool water to remove all surface dirt.
Put a buffing pad on a dual-action buffer and pour a quarter-sized amount of liquid rubbing compound on the pad.
Work the buffer in small circular motions so it doesn't sit in one area for longer than a few seconds.
It’s not reflective as such. What you are seeing are metallic, pearlescent, and “mica” finishes, where tiny shiny particles are mixed into the paint, and sometimes also the clear coat. These particles are small enough to stay encapsulated within the paint itself.
Body paint matching is an art, and only an experienced auto body shop can accurately match new paint to an original finish. All automotive paints have codes specific to the color, but there are thousands of variations and shades. Additionally, color variations from original are inevitable because of normal aging.
With a clear coat over the top, there’s millions of tiny refracted reflections from the sun or other light bouncing off these particles. This gives an iridescent sheen under the right light, but isn’t reflective in the true sense like the red reflectors on the rear of a car, or reflective tape applied to emergency vehicles.
