Bare Surface Preparation

Bare Substrates*: Steel, Galvanized Steel, Aluminum or Fiberglass *Note: With the inconsistencies of substrates, consult your local SHERWIN-WILLIAMS Representative for system recommendations and substrate testing.

1) Solvent clean with SHER-WILL-CLEAN® Solvent Cleaner R7-K156 or AQUA-MATE® Low VOC Surface Cleaner W4-K157 and wipe dry with a clean, dry cloth.

2) Mechanically abrade all bare metal. For hot-rolled steel, a media blast is required to remove any surface impurities.

3) Solvent clean with SHER-WILL-CLEAN® R7-K156 or AQUA-MATE® Low VOC Surface Cleaner W4-K157, wipe dry with a clean, dry cloth. For hot-rolled steel, proceed to step #4.

4) Apply 2-3 medium coats of G.B.P.® Etching Filler E2-G980 or one double coat of CORROSION SHIELD™ E2-G973. Or treat bare steel areas with MET-L-ETCH™ Steel Cleaner W4-K288 followed by MET-L-Mate® Phosphate Conversion Coating W4-K289. Treat bare aluminum with DUAL-ETCH® Metal Cleaner and Conditioner W4-K263.

Pre-Painted Surface Preparation

1) Wash surfaces with a mild detergent in hot water. Rinse well and wipe dry with clean, dry cloth.

2) Solvent clean with SHER-WILL-CLEAN® Solvent Cleaner R7-K156 or AQUA-MATE® Low VOC Surface Cleaner W4-K157 and wipe dry with a clean, dry cloth.

3) Grind off paint and remove all rust. Fill as needed using Sherwin-Williams NO-STAIN(TM) Premium Light-Weight Body Filler D2-A136. Allow body filler to tack up and shape as needed.

4) Sand repair area and featheredge using 80, 180, 280 and finish with 320 grit treated sandpaper on a random orbital sander. Use SHER-WILL-CLEAN® Solvent Cleaner R7-K156 or AQUA-MATE® Low VOC Surface Cleaner W4-K157 to remove sanding residue before recoating.

5) Apply 2-3 single wet coats of G.B.P. Etching Filler E2-G980 or E2-G983 to bare metal and body filler to achieve 1.0 mil minimum. OR, treat bare steel areas with MET-L-ETCH Steel Cleaner W4-K288 followed by MET-L-MATE Phosphate Conversion Coating W4-K289. Treat bare aluminum with DUAL-ETCH Metal Cleaner and Conditioner W4-K263. (NOTE: Use W8-A2500 to meet California VOC compliant recommendations)

6) Apply ULTRA-FILL II Primer-Surfacer P6-H49, P6-A48 or COLOR-PRIME Tintable Primer-Surfacer P6-A47 as needed. Block sand with 180 to 280 grit treated sandpaper.

7) Finish sand repair area with 320 grit treated sandpaper on a random orbital sander.

8) Prep entire blend area or panel by water sanding with 1000-1200 grit or scuff with a gray scuff pad and USP-90 Scuffing Gel.

9) Re-clean thoroughly with R7-K156 or W4-K157.

10) For best results on larger repair areas use ULTRA-FILL II E6-H59, EPOXY PSE-4600 or PRIME-SHIELD E2-A820.

Mixing Procedures

Color Activation

Blending Clear Activation and Reduction

Application Procedures

1) Mask the adjacent panels or blend areas with masking paper. Only expose the repair area.

2) Apply color over repair area until hiding is achieved, allow 10 minute flash between coats. The second or last coat extends out into blend area.

3) Immediately after last coat of color, using a lower air pressure, apply one or two light coats of blending clear over the wet blended color to melt blend edge arcing the spray gun at the end of each stroke.

4) Using a clean gun, melt in edge of clear with Blending Solvent US-3. Spray 2 to 3 light coats at 6 to 8 pounds cap pressure for HVLP or 25 psi using half trigger for conventional.
NOTE: Do not spray into unsanded areas

Buffing Blend Area

1) Allow finish to cure.

2) If sanding is needed for dirt or smoothing the blend area, use 1500 to 2000 grit paper wet.

3) Buff blend area by machine with UPC-10 Polishing Cream or a quality microfinishing compound followed by machine glaze UMG-30 or equivalent. Hand glaze if needed.

Important Notes

1) For additional flow in hot/humid weather, add up to 2 ounces more of reducer GR-1073 or GR-1070 per sprayable gallon of GENESIS® 3.5 VOC.

2) For faster cure time, add up to 3 ounces of Accelerator GA-1097 per sprayable gallon of color. Potlife will be reduced to 1 hour. Refer to GENESIS® 3.5 Data Sheet #1898 for allowable VOC requirements.

3) Force dry using IR for 10 minutes on low for flash and 20 minutes on high or until firm. Position Infra-Red lamp no closer than 36 inches from the part.

4) Decals may be applied after 72 hours. Lower temperatures, heavy film thickness, poor air movement, thick decals, foiled based decals, etc., will extend dry time before decals may be applied.
