ACDelco GM OE Summit White Touch-Up Paint Pen (WA8624)

A four-in-one applicator matched to GM factory paint code WA8624 (Summit White / Olympic White): abrasive prep tip, piston pen tip, brush applicator, and a clear coat chamber in a half-ounce package. Reviewers on GM trucks and SUVs confirm accurate color match after cure — fresh paint reads slightly brighter until it settles overnight. Four thin brush coats at 30-minute intervals produces a flush result on chips up to a quarter inch; the repair blends acceptably from two to five feet. The clear coat adds durability; reviewers confirm the repair holds on daily-driver vehicles.

Best for GM vehicle owners (Chevy, Buick, GMC, Cadillac) with small stone chips where acceptable-from-a-few-feet is the standard. Skip it if the chip has reached bare metal — no primer is included; paint over unprimed bare metal will not hold long-term. Not appropriate for non-GM vehicles; WA codes cover only GM makes.

The label confirms a WARNING signal word, flammable vapor caution, and a California Prop 65 warning. No exact SDS for this part number was found — the related SDS for the same ACDelco lacquer line (Sherwin-Williams manufacture) documents ketone and ester solvents that build vapor in enclosed spaces. Apply outdoors or with the garage door open. Situational eye and skin protection is appropriate. The pen format produces substantially lower vapor exposure than aerosol alternatives.
