ACDelco Four-In-One Touch-Up Paint Pen for GM Summit White (WA8624) 0.5 fl oz — Factory Match, Clear Top Coat Included

ACDelco's GM Original Equipment Four-In-One Touch-Up Paint Pen in Summit White/Olympic White (WA8624) is a compact repair solution that matches factory GM paint and includes a four-function applicator plus clear top coat for small to medium chips and scratches.

Keep your GM vehicle looking its best with a touch-up pen engineered to the same specifications used in production. This 0.5 fl oz pen carries the exact GM color code (WA8624) to deliver an accurate match for Summit White/Olympic White finishes. The product pairs a factory-formulated paint with a multi-function applicator so you can clean, prep, apply, and finish paint in tight areas without specialized tools.

How does the four-in-one applicator simplify paint touch-ups?

The integrated applicator combines surface prep and two paint-delivery methods in one tool, reducing the number of steps and items you need. With the abrasive prep tip you remove loose material and rust; the piston pen-tip dispenses controlled amounts of paint into narrow gouges; and the brush-style tapper covers larger chips smoothly.

• Abrasive prep tip for scraping and rust removal
• Piston pen-tip for precise dot application in fine scratches
• Brush/tapper applicator for feathering and filling wider chips
• Clear top coat included for sealing and gloss matching

Will this pen match my GM vehicle’s Summit White/Olympic White paint?

Yes — the paint is produced to match GM factory color code WA8624, ensuring consistent shading and formulation used in GM assembly plants. Color may vary slightly with age, previous repairs, or environmental fading, so confirm the code on your vehicle first for the best result.

• Contains GM factory original color matching code WA8624
• Formulated using GM-approved pigments and binders
• Designed to replicate factory gloss when sealed with included clear coat

What steps give the most durable, invisible finish?

Preparation and layering matter: clean and dry the area, use the abrasive prep tip to remove loose paint, apply thin layers with the piston tip or brush, then finish with the clear coat. Allow appropriate drying time between coats for adhesion and to prevent runs.

• Clean area with mild solvent and dry thoroughly
• Use prep tip to remove loose paint and rust
• Apply thin, even layers; let each layer flash before next coat
• Finish with included clear top coat for protection and shine

How much area will this 0.5 fl oz pen cover and when should I choose professional repair?

A single 0.5 fl oz pen is intended for spot repairs—small chips, narrow scratches, and localized scrape areas—not whole-panel coverage. If the damage spans large areas, affects primer or metal extensively, or alters panel shape, a full respray or body-shop service is recommended for structural and color consistency.

• Best for minor chips and thin scratches across multiple spots
• Not designed for full-panel repainting or deep structural repair
• Use a body shop when rust has penetrated beneath the metal or primer

Who is this for: The ACDelco GM Original Equipment Summit White/Olympic White WA8624 touch-up pen is aimed at GM owners who want a factory-color match for small cosmetic repairs — drivers who prefer a DIY fix over immediate body-shop work, enthusiasts maintaining resale value, and fleet managers needing a compact, OE-validated solution for routine blemish control.
