GM WA8555 Black Basecoat With Reducer Gallon (Basecoat Only)

This GM WA8555 Black Basecoat With Reducer Gallon (Basecoat Only) Paint Kit includes the basecoat and reducer you need to lay down a smooth, even foundation before applying your clearcoat. Please note that this listing is for basecoat paint and reducer only — a clearcoat is required to complete the finish.

Auto Paint HQ’s OEM basecoat system uses advanced color-matching technology to deliver accurate OEM-style results with excellent coverage. The basecoat sprays smoothly, covers quickly, and mixes 1:1 with the included universal urethane reducer for a consistent, professional-grade application.

This product is intended for overall refinishing. Because various conditions can impact final color appearance, we cannot guarantee a precise color match for spot repairs or blending. If used for small repairs, please understand that no color-match claims are made.

Made in the USA.

Selecting the Right Reducer Speed
