What Chevrolet 42U Deep Bluish Green Pearl Looks Like

Paint code 42U is Chevrolet's Deep Bluish Green Pearl, a green with a tri-coat pearl finish. Pearl pigment shifts the shade slightly as the viewing angle changes. Its depth comes from a color layer over a ground color. We mix it to the factory formula. Matching your factory paint? Check that the paint code on your vehicle's label reads 42U.

What You Need to Spray It

Deep Bluish Green Pearl is a Tri-Stage color, an advanced job. It requires the APU122 undercoat for the correct hue and coverage; without it, the color won't match. Spray order: Gray AP-7541g Sealer, then the APU122 undercoat, then Deep Bluish Green Pearl, then Alpha Automotive Clearcoat for gloss and protection. New to this?

Spraying Tips for Tri-Coat Pearl

Spray a test panel to find how many mid-coats give the match, then use that number on every panel. Blend into the next panel on spot repairs; pearl shows small differences more at an angle.

STEP 1 – CLEAN THE SURFACE

1 - Wash with soap and water, rinse, and dry completely.

3 - Wipe dry with a clean, lint-free towel.

STEP 2 – SCUFF / SAND FOR ADHESION

If Raw Plastic / Polyurethane: Evenly scuff bare plastic or raw surfaces. These will also need to be adhesion promoted prior to paint using our WolfBite Adhesion promoter.

If Good Condition OEM Paint: Sand smooth or glossy paint with P320-P400 grit sand paper or Scuff Pad until uniformly dull with no glossy areas.

If Surface Needs Bodywork or heavy scratches removed: Sand the damaged areas with 180 grit (feathered out into the panel) then do your bodywork. Finish in 220 Grit sanding. Then spot prime with high build primer - fading the primer out into the rest of the sanded panel covering the bodywork and any 220 grit scratches. (the good condition areas of the panel should have been sanded in 320-400 or scuff pad). Lastly, after the high build primer is dry and ready to be sanded (check tds for timeline), sand with 320-400 to match the rest of the panel.

After The above prep: Remove dust with compressed air or a clean microfiber towel.

STEP 3 – FINAL WIPE & TACK

1 - Wipe the surface again with isopropyl alcohol or wax and grease remover.

2 - Allow solvents to fully evaporate.

3 - Lightly wipe with a tack cloth immediately before spraying. Do not press hard. (optional but great step)

STEP 4 – SET UP YOUR SPRAY AREA

1 - Use a well-ventilated, well-lit area with good extraction fans

2 - Ideal conditions are 65–75°F (18–24°C) with 40–60% relative humidity.

3 - Keep the area free of open flames, sparks, or ignition sources.

4 - Wet the floor if your space allows to keep dust down

5 - Cover any items or areas in your space that you do not want to get overspray on

STEP 5 – PERSONAL PROTECTION

1 - Wear a respirator rated for organic or solvent vapors.

2 - Use nitrile gloves and safety goggles.

3 - Wear a paint suit

STEP 6 – SHAKE THE CAN

1 - Shake vigorously for 45–60 seconds.

2 - Invert the can several times while shaking to fully mix pigments and metallics.

STEP 7 – TEST SPRAY

ALWAYS DO A TEST SPRAY + SPRAY OUT CARD IF DOING OEM SPOT JOBS

1 - Spray on cardboard or a scrap panel.

2 - Confirm even spray pattern, correct color, and proper atomization.

3 - Adjust the spray can's nozzle to match your spray style or surface.

4 - If the can is not operating correctly, remove the cap completely, reseat it on the can, and twise the entire nozzle 360 degrees. Since our cans are made to order, sometimes there is slight paint build up and reseating the nozzle corrects this.

STEP 8 – SPRAYING TECHNIQUE

1 - Hold the can 5–6 inches from the surface.

2 - Keep the can perpendicular, 90 degrees to the panel at all times.

3 - Move at a steady speed using smooth, even passes. You are looking for medium wet coats NOT super wet, pooling coats.

4 - Overlap each pass by 50 percent.

STEP 9 – TRIGGER CONTROL

1 - Begin moving before pulling the trigger. Start off of the panel then move onto the panel. This avoids build up on edges.

2 - Fully depress the trigger while spraying.

3 - Release the trigger completely at the end of each pass.

4 - Stop spraying after clearing the panel edge by an inch.

STEP 10 – COATS & FLASH TIMES

1k Primer/Sealer

1 - Spray a medium wet coat on the entire panel (if not blending oem paint) to achieve a 75% coverage. This fills in the sanding scratches as well as gives a uniform , required ground coat color for the next steps.

2- Allow to flash dry for 5-15 minutes. Time depends on the product and environment.

3 - Apply the second medium-wet coat to achieve full coverage

4 - Allow to dry for 30 minutes or until the wet look fades so a dull, even finish and is completely dry to the touch.

GROUNDCOATS or SOLID COLORS (BEFORE MIDCOATS IF APPLICABLE)

This is for our Base Black, OEM Undercoats or solid colored basecoats. Not all projects require this step.

2 - Allow to flash 5-15 minutes or until the wet look fades so a dull, even finish. Time depends on the product and environment.

3 - Apply the second medium-wet coat to achieve full coverage

4 - Allow to flash 5-15 minutes or until the wet look fades so a dull, even finish. Time depends on the product and environment.

5 - Apply a Third medium wet coat if the color is not 100% covered and even at this point. This will vary based on the color and product being sprayed.

4 - Flash another 15-30 minutes. Until the surface is even, dull, an dry to the touch.

MIDCOAT , CUSTOM COLORS , OR METALLIC/ PEARL OEM

This is for coverage over required groundcoats , not "ghost effect"

1 - Apply medium coats over the required groundcoat for your color.

2 - Flash 5–15 minutes between coats or until tack-free.

3 - Apply additional coats until the desired color depth is achieved. Most custom and oem colors require 2-4 medium coats - check color description or compare to existing oem panels

4 - Apply 1 light "control" coat to make sure all of the pearl or metallic is even and not splotchy or "tiger striped"

5 - Once the entire surface, even cracks and crevices, is completely dry to the touch, wait 15 minutes in a temperature-controlled paint booth. In any other environment at 70°F or warmer, wait 30 minutes to 1 hour. Then move on to the topcoat step.

EFFECT PEARL / COLORSHIFT COAT

This is for effect over light groundcoats (not for coverage)

1 - Apply one light effect coat at approximately 25 percent coverage.

2 - Allow 5-15mins for the coat to flash before adding another light coat (if you want to add more effect)

Repeat as many times to your preference of effect and coverage.

3 - Once the entire surface, even cracks and crevices, is completely dry to the touch, wait 15 minutes in a temperature-controlled paint booth. In any other environment at 70°F or warmer, wait 30 minutes to 1 hour. Then move on to the topcoat step.

STEP 11 – CLEANUP & STORAGE

2 - Keep away from direct sunlight.

3 - Avoid freezing conditions.

4 - Do not store above 120°F (49°C).

QUICK TROUBLESHOOTING

2 - Runs or sags mean the can is too close or moving too slowly.

3 - Continue to shake and agitate the can between coats- Repeat step 6

4 - If ever unsure the color is 100% covered (and you are going for coverage) - one extra coat is always a good idea.
