Mercedes-Benz has approved PPG DP4000 2K primer by PPG’s automotive refinish business for worldwide refinish repairs of all Mercedes-Benz cars. The 2K primer is designed to help body shops cut costs and increase productivity. The technology underpinning PPG DP4000 2K primer enables body shops to dispense with the need to sand the electrocoat substrate on new panels. This can reduce the process time for primer application by up to 50 percent and ensures that the corrosion protection of the electrocoat is maintained. PPG DP4000 2K primer is capable of sealing off the most sensitive substrates and is suitable for direct application over unflatted new panels coated with OE electrocoats, and also most rigid plastics.
