- Stage 1: PRETREATMENT Hot alkaline cleaning of the metal following by roll-on application of a Chromatic Conversion Coating, which prevents corrosion and improves paint adhesion.
- Stage 2: PRIMER A specially formulated polyester primer is applied, designed for flexibility and corrosion resistance.
- Stage 3: FINISH COAT A polyester-resin top coat, designed for greater exterior durability and flexibility, is applied and then baked.
