ACDelco White Diamond Pearl WA800J Touch-Up Paint .5 oz Pen — GM OE Match with Four‑in‑One Applicator & Clearcoat

ACDelco's GM Original Equipment White Diamond Pearl (WA800J) Four‑in‑One Touch‑Up Paint is a factory‑matched .5 oz pen that repairs small chips, scratches and scuffs with an integrated brush, piston tip and clear topcoat for a finished shine.

This compact touch‑up solution is engineered to match GM factory colors and deliver a simple, at‑home repair for minor body blemishes. The .5 fluid ounce package contains paint formulated to the GM color code WA800J (White Diamond Pearl) and includes a multi‑functional applicator that helps you address different damage sizes without mixing paint or renting equipment.

How accurate is the color match to my GM vehicle?

The paint is manufactured to GM Original Equipment standards using the WA800J factory color code, so it aligns with the OEM shade as applied at the factory. That reduces visible differences when used on intact clear‑coated panels. For best results, clean and lightly sand the damaged area before application and verify the code on your vehicle to confirm a match.

• Factory color code: WA800J (White Diamond Pearl)
• Manufactured to GM Original Equipment (OE) specifications
• Includes clear topcoat for glossy finish integration
• Ideal for spot repairs where the factory paint is intact

What does “four‑in‑one” applicator mean and when should I use each mode?

“Four‑in‑one” refers to multiple application options inside a single pen: a piston‑style fine tip for pinpoint dots, a wider brush for chips or thin scratches, the paint reservoir and an included clearcoat. Use the piston tip for pinpoint stone chips, switch to the brush for longer scratches or edge repairs, and apply the clear topcoat at the end to blend gloss and protect the touch‑up.

• Piston tip: precise dots for tiny chips
• Brush applicator: fills wider scratches and shallow gouges
• Integrated paint reservoir: no separate mixing required
• Clear topcoat: restores shine and helps seal the repair

How long will the repaired area last and how should I prepare the surface?

Longevity depends on proper prep and exposure conditions; a clean, dry surface and correct technique improve durability. Lightly scuffing and cleaning the area removes loose paint and contaminants, allowing the touch‑up to adhere better. After the paint cures, the clearcoat helps resist fading and wear, but avoid heavy polishing for several days.

• Prep: wash, dry, and remove loose paint; lightly sand if needed
• Application: use small, even strokes; allow drying between layers
• Cure time: follow ambient temperature recommendations before polishing
• Care: avoid abrasive washing or compounding immediately after repair

This touch‑up pen is designed for quick cosmetic repairs rather than structural bodywork. It’s not a replacement for panel refinishing or professional color blending on large areas; use it for spot fixes to maintain appearance and help prevent corrosion until a full repair is performed.

Who is this for: Vehicle owners who drive GM‑brand cars and trucks and need a compact, factory‑matched touch‑up solution for small chips and scratches. It’s suited to DIYers wanting an OEM color match and easy application without specialized equipment, plus service technicians needing an on‑hand pen for fast spot repairs.
