Car paint includes a top clear coat which is normally about 30 micrometers thick. Most paint flaws exist in this clear coat. Swirl, contaminants and scratches can often be removed with polishing. When we polish the a vehicle finish it is essentially a very fine sanding. We remove about .3 micrometers of clear coat when polishing. This allows us to bring to finish back to show room quality.
Our process may start with Menzerna 1500 which has more aggressive cut and work our way up to the 4500 which is much more polish and less cut. Once we get the finish complete to where the paint looks and feels smooth we finish it off with a menzerna polymer wax.
This process often requires many passes over the full car and can take up to an entire day to get it looking as nice as possible.
