The ACDelco GM Original Equipment 19367651 Black (WA8555) Four-In-One Touch-Up Paint Pen is a factory-matched solution designed to repair minor paint imperfections on compatible General Motors vehicles. This 0.25 fluid ounce pen delivers precise color matching to the original factory finish, utilizing the same pigment formulation used in GM assembly plants. The four-in-one design integrates a primer, basecoat, clear coat, and a blending nozzle into a single applicator, allowing users to address stone chips, scratches, and scuffs with minimal effort. The tip provides controlled application for both small spots and slightly wider coverage, reducing the risk of excess paint. Formulated for durability, the paint resists fading and chipping once fully cured, helping maintain the exterior appearance over time. The pen-style packaging ensures convenient storage and portability, making it suitable for touch-ups in various settings. This product is intended for use on Black (WA8555) paint codes specifically, and it supports a straightforward application process that involves cleaning the surface, applying the paint in thin layers, and allowing adequate drying between coats. The quick-dry formula aids in efficient repairs, while the compatible color match helps blend with the existing paint. As an affordable maintenance option, this touch-up pen offers a practical alternative to professional resprays for small-area blemishes. It is compatible with a wide range of GM models from various production periods, though verifying the exact paint code is recommended before use. The compact size allows multiple pens to be kept on hand for different colors.

This tool is designed to help vehicle owners preserve the aesthetic condition of their car with a reliable, value-focused approach to paint care.
