Chevrolet Cruze Repair Manual: 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.

Lower Anchors and Tethers for Children (LATCH System)
The LATCH system secures a child restraint during driving or in a crash.
LATCH attachments on the child restraint are used to attach the child restraint
to the anchors in the vehicle. This system is designed to make installation of a
child restraint easier.
Make sure that a LATCH-compatible ch ...
Relieving Fuel Pressure Warning
Warning: Remove the fuel tank cap and relieve the fuel system
pressure before servicing the fuel system in order to reduce the risk of
personal injury. After you relieve the fuel system pressure, a small amount of
fuel may be released when servicing the fuel lines, the fuel
injection pump, or ...
Installation Procedure
Cut the front compartment front rail in corresponding locations to fit
the remaining original panel. The sectioning joint should be
trimmed to allow a gap of one-and-one-half-times the metal thickness at the
sectioning joint.
Create a 50 mm (2 in) backing plate from the unused porti ...
