OVERVIEW:
This bulletin involves removing overspray which can be a result of industrial fallout and/or a poor refinishing process.
DISCUSSION:
Depending on the severity and extent of overspray on painted surfaces the removal process will vary. Always begin using the least
aggressive method. An example of overspray is shown in (Fig. 1).
1. Before removing any overspray, wash the effected area with soap and water as shown in (Fig. 2).2010 Jeep Truck Grand Cherokee 4WD V63.7L
10.52SS
Page 123
2. Work in a 12"(305mm) x12"(305mm) area at a time and apply Meguiars Final Inspection or a detail spray equivalent to the effected
area (Fig. 3).
3. Using a clay bar work in a unidirectional pattern while the detail spray applied in Step # 2 is still wet as shown in (Fig. 4).
NOTE:
Do not move the clay bar in a circular direction on the panel surface as it will create scratches.
4. As the overspray is removed, remove the detail spray residue with a microfiber cloth and continue to the next effected area until all
the overspray is removed (Fig. 5).
5. If overspray cannot be removed with a clay bar and Meguiars Final Inspection or equivalent, proceed to Step # 6.
6. Use a D.A. polisher with a foam finishing pad and Meguairs So1o Cut & Polish Cream Or an equivalent compound and polish cream,
working in a 12"(305mm) x12"(305mm) area. Was the overspray removed?2010 Jeep Truck Grand Cherokee 4WD V63.7L
10.52SS
Page 124
a. Yes >>> Continue using this method on the other affected painted surfaces and remove polishing residue with a microfiber cloth as
shown in (Fig. 5).
b. No >>> Proceed to Step # 7.
7. Use a rotary buffer with a foam polishing pad set to a preferred RPM and Meguairs So1o Cut & Polish Cream Or an equivalent
compound and polish cream, working in a 12"(305mm) x12"(305mm) area. Was the overspray removed?
a. Yes >>> Continue using this method on the other affected painted surfaces and remove polishing residue with a microfiber cloth
as shown in (Fig. 5).
b. No >>> Proceed to Step # 8.
NOTE:
A rotary buffer must be used by a trained technician as it can permanently damage the painted surface if not used correctly.
Damaged areas can only be repaired by refinishing the affected vehicle panel. Prior to using a rotary buffer measure the paint
thickness using Gauge #PRETG2X or equivalent to determine clearcoat or singlestage paint thickness before and after the repair.
CAUTION:
Do not remove more than 0.2 mils of clearcoat when polishing. Most vehicles have 1.5 mils of clearcoat film thickness.2010 Jeep Truck Grand Cherokee 4WD V63.7L

Page 125
8. Lightly wet sand the overspray with Meguiars unigrit 2500 wet sandpaper (or equivalent) with a Mequiars sanding pad (or equivalent)
in a unidirectional pattern until the overspray has been removed or more than 0.2 mils of clearcoat has been removed (Fig. 6).
9. Use a rotary buffer with a cutting polishing pad set to a preferred RPM and Meguairs So1o Cut & Polish Cream Or an equivalent
compound and polish cream, working in a 12"(305mm)x12"(305mm) area.
10. Remove the compound residue with a microfiber cloth to verify the scratches have been removed. Were the sand scratches
removed (Fig. 5)?
a. Yes >>> Proceed to Step # 11.
b. No >>> Repeat Step # 9.
CAUTION:
Do not remove more than 0.5 mils of clearcoat when wet sanding an
polishing. Most vehicles have 1.5 mils of clearcoat film thickness.
11. Use a rotary buffer with a foam polishing pad set to a preferred RPM and Meguairs So1o Cut & Polish Cream Or an equivalent
compound and polish cream, working in a 12"(305mm) x12"(305mm) area. Was the overspray removed?
a. Yes >>> Continue using this method with Step # 10 on the other affected painted surfaces and remove polishing residue with a
microfiber cloth as shown in (Fig. 5).
b. No >>> Suspect area refinish will be required to remove overspray.2010 Jeep Truck Grand Cherokee 4WD V63.7L

Paint Clearcoat Blending During Refinish Process
NUMBER: 3100213
GROUP: Collision Bulletin
DATE: January 31, 2013
SUBJECT:
Blending Clearcoat During The Refinish Process
OVERVIEW:
This bulletin discusses Chrysler's position against the use of partial clearcoat blending.
DISCUSSION:
Partial clearcoat blending is not an approved warranty repair process for Chrysler vehicles. Partial clearcoat blending is a process that
generally involves adding solvents to a paint manufacturers clearcoat mixing formula to reduce the viscosity. This will not only degrade
the durability of materials but it could also produce additional emissions. Partial clearcoat blending is achieved by adopting processes
that are typically used to transition basecoat color on repair areas. Clearcoat should always be applied to the entire surface area of a
body panel and mixed to manufacturers specifications. Any vehicle repaired with the partial
clearcoat blending process will prematurely fail and eventually result in a clearcoat delamination condition. An example of clearcoat
blending is shown in (Fig. 1).
As shown in (Fig. 1) clearcoat is not applied to the entire quarter panel surface area, but only to a small portion. The repair area will
initially appear sufficient but depend on how the process was performed the repair area will begin to degrade in 6 months to 3 years.2010 Jeep Truck Grand Cherokee 4WD V63.7L

Page 130
Clearcoat (1) has been applied to the entire quarter panel in (Fig. 2) and basecoat (2) was applied to cover the repair area, which is the
proper repair process.
NOTE:
This figure is used for demonstration purposes only. Most quarter panel repairs require clearcoat to be applied to the entire side
aperture which typically ends at the cowl adjacent to the front fender.
