ACDelco GM Original Equipment touch-up pen Switchblade Silver Metallic WA636R — .5 oz four-in-one applicator, factory-matched

ACDelco's GM Original Equipment Switchblade Silver Metallic (WA636R) Four‑In‑One touch‑up pen is a factory‑matched .5 oz paint tool designed to repair small to medium scratches and chips on GM vehicles.

If you need a compact, easy‑to‑use solution to hide everyday dings and restore the original factory color, this ACDelco GM OE touch‑up pen delivers a precise match for GM paints. Engineered and validated by General Motors, the WA636R formula comes in a four‑in‑one applicator that combines cleaning, prep and two paint delivery options in a single pen. The result is a better cosmetic repair in less time than mixing bottles or re‑spraying small areas.

How does the four‑in‑one applicator simplify small repairs?

The integrated design includes an abrasive prep tip, a piston pen tip and a tapered brush so you can prep and apply without switching tools. The abrasive tip helps remove loose paint and rust; the piston tip meters paint for narrow scratches, while the brush covers larger chips evenly.

• Abrasive fiberglass prep tip for cleaning and feathering edges
• Piston pen tip for controlled, drip‑free applications
• Tapered brush for blending and covering larger blemishes
• Single‑handed operation speeds up touch‑ups

Will this pen match my vehicle’s factory color?

Yes — ACDelco GM Original Equipment touch‑up paints use GM factory color matching codes to replicate exact OEM shades. Use the paint code from your vehicle to confirm WA636R Switchblade Silver Metallic is the correct match for your car or truck.

• Paint formula tied to GM color code systems for accuracy
• Factory validation ensures consistent hue and metallic fleck
• Compact .5 oz size designed for spot repairs, not full panels
• Best for chips, stone dings, narrow scratches and edge nicks

How do I use the ACDelco Switchblade Silver touch‑up pen effectively?

Start by cleaning the area and using the abrasive prep tip to remove loose paint and oxidation. Apply small amounts with the piston tip for thin scratches and switch to the brush for wider chips; allow drying between layers and finish by blending with surrounding paint.

• Clean and dry the damaged area before starting
• Use the pointed abrasive edge to remove corrosion and loose flakes
• Apply thin coats with the piston tip, finishing with the brush as needed
• Allow adequate drying time; multiple thin coats outperform one heavy coat
