ACDelco Iridium Metallic WA121V Touch-Up Paint Pen — 0.5 oz Four-in-One Repair Kit, Base + Clear

ACDelco's GM Original Equipment Iridium Metallic (WA121V) four‑in‑one touch‑up paint pen is a compact 0.5 oz repair kit that combines base color, clear coat, and a multi‑tip applicator to restore small chips and scratches to factory color match.

This compact repair tool is formulated to match the GM Iridium Metallic (WA121V) finish and comes from ACDelco's GM Original Equipment line. It pairs .25 oz of base paint with .25 oz of clear coat inside a single, easy‑to‑use cartridge and includes a built‑in mechanical agitator to keep the blend uniform. The design targets everyday damage such as stone chips, door dings, and small scratches where a full respray isn't needed, while preserving the factory color code validated by GM engineers.

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

The four‑in‑one tool combines cleaning, precise application, broader brush coverage, and finishing in one pen. You get a fiberglass prep tip, a piston pen tip for pinpoint jobs, a tapper brush for wider chips, and an internal agitator to keep pigments mixed.

• Fiberglass cleaning tip to remove contaminants before painting
• Piston‑style pen tip for tight scratches and narrow chips
• Tapper brush applicator for larger damaged areas
• Mechanical agitator for consistent color and texture

Will this restore the original GM Iridium Metallic color accurately?

The paint is formulated to the GM factory color code WA121V so it aims to match the original Iridium Metallic finish. Because the kit contains GM‑specified pigment and a clear coat, it achieves a close visual match when applied correctly on clean, prepared surfaces.

• Includes GM color code WA121V for accurate formulation
• Clear top coat included for gloss and protection
• Best results when used on properly prepped, clean surfaces
• Small touch‑ups blend best under similar lighting conditions

What kinds of damage is this touch‑up pen intended to fix?

This pen is designed for minor body blemishes—stone chips, shallow scratches, and small areas of paint loss that don’t require body‑shop level work. It’s not a replacement for collision repair but a convenient option for everyday nicks that affect appearance.

• Stone chips on bumpers, hoods, and fenders
• Shallow scratches that haven’t penetrated heavy dented metal
• Paint loss around door edges or trim areas
• Quick onsite cosmetic fixes without removing panels

How do I get the best finish using this pen?

Preparation, thin coats, and curing time are the keys. Clean the area, remove loose paint, use the fiberglass prep tip to degrease, apply the base in thin layers, allow each coat to tack, then finish with the included clear coat for gloss and protection.

• Clean and dry the surface before applying paint
• Use the piston tip for precision, brush tip for coverage
• Apply multiple thin coats rather than one thick coat
• Finish with the clear coat and allow recommended drying time

Who is this for: The ACDelco Iridium Metallic (WA121V) four‑in‑one touch‑up paint pen is aimed at GM owners—Chevrolet, Buick, GMC, and Cadillac—who want a quick, factory‑matched cosmetic repair for small chips and scratches without visiting a body shop. It’s ideal for DIYers, fleet managers, and anyone who prefers to maintain the original GM color finish for resale value or appearance between professional repairs.
