Chevrolet Cruze Repair Manual: Paint Gauges

Chevrolet Cruze Repair Manual / Body repair / Paint and Coatings / Paint Gauges

Paint thickness gauge. measure the total thickness of the vehicle finish. It is important to accurately measure the thickness of the finish on each vehicle as the thickness of the finish will vary on each vehicle. Use a paint gauge before the sanding process in order to accurately measure how much finish there is to remove before, during, and after the sanding process. Paint gauge. range from magnetic pull type to sophisticated electronic types, and are available from a variety of sources. The older magnetic type gauge., at best have a 5 percent accuracy range and are not sensitive enough to detect removal of 0.02 mm 0.5 mil (0.0005 in) clearcoat. The newer type magnetic gauge.

have improved accuracy ranges. Most gauge. are confined to checking either ferrous metal, steel, non-ferrous metal, or aluminum panel.

At this time, there are no viable gauge. for reading film thickness on composite (SCM doors, RIM fenders) panels. The more sophisticated (ETG) electronic paint thickness gauge. digital type gauge. are able to read film thickness on both ferrous and non-ferrous metal panel.

Digital ETG gauge. may have an accuracy range of 1 percent and include thickness standards for recalibration. The following paint thickness gauge. are available. Call 1-800-GM-TOOLS for information:

Clearcoat Thickness

The clearcoat on the vehicle is typically 0.059-0.078 mm (1.5-2 mils [0.0015-0.0020 in]) thick. The clearcoat contains ultraviolet screeners. Removing more than 0.5 mils (0.019 in) of the clearcoat may result in early paint failure.
