You should avoid using surface cleaners that contain ammonia on ENVIROBASE® High Performance EPW115 or AQUABASE® Plus P950-5505 waterborne primers prior to topcoating. Cleaners that contain ammonia (glass cleaners or DELTRON® DX394 cleaner) can soften the film.

For a final clean before topcoating, you can safely use Deltron DX330 or ONECHOICE® SXA330 wax and grease removers, or OneChoice SWX350 waterborne pre-cleaner.

Over the years, there has been situations where several GM plants have had issues with their code labels and the WA color code was omitted. Best solution:

  1. Contact a local GM dealer and provide the Vehicle Identification Number (VIN)
  2. Request the Model, Year and Color information including the correct code
  3. Validate this information with a variety of PPG or NEXA AUTOCOLOR® brand color tools (Paint It, Color Information Books or Variant systems)
  4. Always confirm the correct color by spraying a test panel
