ACDelco White Diamond Pearl (WA800J) Touch-Up Paint Pen — 0.5 oz Four‑in‑One with Clear Coat for GM Vehicles

ACDelco White Diamond Pearl (WA800J) Four‑In‑One Touch‑Up Paint is a factory‑matched .5 oz pen kit designed to repair small chips and scratches on GM vehicles with a built-in clear coat for a finished look.

If your Chevrolet, Buick, GMC or Cadillac has minor paint damage, this compact touch‑up pen supplies GM factory color matching in White Diamond Pearl (WA800J). The product comes from ACDelco’s GM Original Equipment line, engineered to the same color and finish standards used in factory production. It’s intended for everyday blemishes—stone chips, parking lot scratches, and edge scuffs—giving a convenient way to restore appearance without a full respray.

How does the four‑in‑one applicator work for different kinds of paint damage?

The kit combines a piston‑style pen tip for precise dots and a small brush for broader areas, plus an integrated clear topcoat to seal the repair. This helps you address both pinpoint chips and longer surface scratches with a single tool, reducing the need for multiple products.

• Piston tip: accurate paint placement for tiny chips and nicks.
• Brush applicator: smooth coverage for larger scratches and seams.
• Clear top coat: adds protection and a matched gloss finish.
• Compact .5 oz size: portable and easy to store in a glovebox or garage drawer.

Will this paint match my GM vehicle’s factory finish?

The formula carries the GM color code WA800J and is made to replicate the White Diamond Pearl shade used by GM. Because it’s part of the GM Original Equipment family, the color and sheen aim to align with factory standards, helping repairs blend with surrounding panels when applied correctly.

• Factory color code WA800J included in the product for precise matching.
• Pearlescent formulation to approximate original pearl depth and sheen.
• Recommended for small to medium blemishes rather than full panel resprays.
• Best results achieved after surface prep and proper layering of paint and clear coat.

How do I use the touch‑up pen for the best result?

Start by cleaning and drying the damaged area, removing loose paint and wax. Apply thin layers—first the colored paint until the chip is filled, let it dry, then finish with the included clear coat; multiple thin coats reduce drips and improve blending.

• Clean area with mild detergent and dry thoroughly before painting.
• Use piston tip for dot filling; switch to brush for feathering or wider chips.
• Allow proper drying time between coats per ambient temperature and humidity.
• Finish with the clear top coat to match original gloss and protect paint.

What should I expect from durability and care after application?

The touch‑up is formulated to restore appearance and provide surface protection suitable for everyday conditions. While it helps shield exposed metal and slows corrosion, it’s intended as a maintenance repair; professional repainting may be preferable for large or structural damage.

• Clear top coat improves resistance to moisture and contaminants.
• Small repairs reduce the chance of rust and further paint loss.
• Not a substitute for professional bodywork on severe damage.
• Keep treated areas clean and avoid harsh chemicals during cure time.

Who is this for: Drivers and DIYers who own GM vehicles finished in White Diamond Pearl (WA800J) and want a compact, factory‑matched solution for minor paint repairs. It’s ideal for maintaining curb appeal between professional service visits, for owners who prefer to fix small chips themselves, and for service departments that need a reliable, OEM‑coded touch‑up option without ordering full‑size paint supplies.
