SHEET METAL PARTS NOW COME IN GREEN OR BLACK PRIMER
If you’ve worked in the auto body repair business for a while, you’re probably accustomed to seeing GM Genuine OE ELPO (e-coated) primed sheet metal parts brandishing that familiar black hue. In fact, it’s been that way for about the past 20 years.
Now, due to an expansion of GM processing facilities and capabilities for its sheet metal products, some of the GM OE ELPO parts you receive may come in green primer, depending on the processing location.
ELPO IS A PROCESS by which organic paint solids are electroplated onto bare metal surfaces to form a barrier against water, salt and other corrosive materials that can penetrate and initiate the oxidation process. ELPO is preceded by an eight-step pre-treatment regimen that effectively ensures that the paint tightly bonds to the metal part. Unlike many aftermarket imitation parts, GM Genuine sheet metal products utilize the OE-specified procedure to provide the same high-quality product that’s found on new vehicles from the factory.
So, whether your next GM OE sheet metal order arrives in green or black, rest assured that it is engineered by GM to provide the same robust rust-proofing properties, quality material and premium specifications that you’ve come to rely on for years.
