IR P100 to P185 Series: DIY Paint & Finish Maintenance

DIY Exterior Finish Care for Ingersoll Rand P100–P185 Portable Compressors

These Ingersoll Rand portable compressors—models P100-WDJU through P185-WJDU—don’t just work hard, they’re built to look good doing it. Each unit is factory-finished with a durable, heat-cured polyester powder coating. With a little routine care, you can keep that finish looking sharp for years to come.

Basic Cleaning Tips

  • To remove dust or pollen: Gently wash with water and mild soap or dish detergent. Avoid scrubbing with rough cloths or pads that could scratch the finish.
  • To remove grease or oil: Use a fast-evaporating alcohol or chlorinated solvent. Be aware that this may dull the paint slightly.

Restoring Faded Paint

If the paint starts to fade or chalk, a commercial-grade, non-abrasive car wax can help bring back some of the original color and gloss. Just make sure the surface is clean and dry before applying.

Touch-Up Painting Instructions

To preserve the factory-quality finish when touching up scratches or chips, follow these steps:

  1. Finish sand the area with 320-grit sandpaper.
  2. Remove all sanding dust using alcohol and clean, lint-free rags. Change rags frequently to avoid spreading debris.
  3. Use tack rags (automotive-grade) to remove any remaining lint or loose particles.
  4. Inspect the surface to ensure it’s free of dirt, fibers, grease, and moisture.
  5. Apply paint using a high-quality, solvent-based automotive liquid paint that adheres to powder-coated surfaces. Do not use water-based or latex paint.

Post-Painting Care

If you’ve touched up the finish, avoid washing the painted area with anything but clean water for at least 30 days to allow proper curing.

Wrap-Up

A clean, well-maintained compressor not only runs better—it reflects how you take care of your equipment. A little time spent maintaining the exterior can go a long way in extending the life (and resale value) of your machine.
