After completing the adhesion test I posted in my previous article, we continued to do the necessary preparation that included, degreasing the complete surface, power washing and grinding the complete surface. The rust areas we ground to the bare steel. We applied 1 heavy coat of Vista Paint Metal Prime, then applied 2 coats of Vista Paint Protec Alkyd Emulsion Semi Gloss. Below is the video of the process of painting over powder coating. I will be doing a follow up video of a adhesion test after a 3 week cure period.
