WHAT IS CERAMIC COATING?
The climb to Cypress Mountain, one of the three North Shore mountain access roads, leaves sand and salt on the front bumper, lower doors and rocker panels of a Sierra or Yukon. A Whistler trip adds 120 km of highway grit each way, especially on a tall truck’s exposed leading edges. GMC ceramic coating is a liquid layer that bonds over sound paint after we clean and prepare it. It adds a thin, hard sacrificial layer that resists light marring and makes road grime easier to wash away. It does not stop a stone chip or seal rust already under the paint. We check the chip-prone front and lower body panels first, then tell you if film makes more sense there. For GMC coating, choose ceramic when you want easier wash care and light-marring resistance; choose film where grit strikes.
