I was watching one of those shows for classic car enthusiasts a couple of days ago. The guys were working on a Lincoln Continental Mk3 and needed to know how much paint they had to spare before attacking it with rubbing compound and spinning cotton mops to remove the surface oxidation. Someone came along with a paint thickness meter, touched the probe on the surface of the paintwork and was able to determine it was 250 microns thick. I'm just wondering what ingenious principle is employed here to make such non-destructive measurements possible, particularly since there are different undercoat and topcoat paints involved and it was able to differentiate between them. Anyone know?
