What happens here
The discussion shifts to the critical importance of the painting process for trailer longevity, especially in harsh environments. Jacob explains Diamond C's extensive DM Coating System, which begins with media blasting (using steel shot, not sand) to aggressively clean mill scale and loose particles from the raw steel. This is followed by a multi-stage wash process using various rinses and a pH balancer to prepare the metal for optimal primer adhesion. The trailers then go through drying ovens to ensure all moisture is removed from every crevice.
Goal: Understand the comprehensive surface preparation steps that are crucial for paint durability and rust prevention.
