Each PPG premium basecoat system utilizes gray shade undercoats to achieve the best color match possible. Sticking to the recommended spectral gray sealer indicated in the color retrieval software will help you achieve the proper color in fewer coats, creating an invisible repair with reduced labor and material costs.

The spectral gray undercoat contributes to the final basecoat color and is critical to matching the OE finish. Once the recommended gray undercoat is applied, coats of color can be applied to “perceived hiding”, allowing the sealer to play its role in the final match. This holds especially true for translucent colors. Using a colored undercoat can create a color shift, compromising the color match, often resulting in more time and material to be used in the repair.

So use the recommended spectral gray undercoat and achieve a flawless repair in fewer coats, with less time and material!
