A stone chip is a $25 fix or a $500 fix. The difference is mostly whether you rush it.
We mix touch-up paint to factory codes all day, every day — 188,000+ colors at last count — so we've heard every version of "I made it worse." This is the process that avoids that.
First: is this actually a touch-up job?
Touch-up paint is for chips and small scratches that are deeper than the clearcoat — you can feel them with a fingernail, and you can see a different color (primer gray, or metal) at the bottom.
- Can't feel it with a fingernail? That's a clearcoat scuff. You don't need paint — you need polish. Paint on top of a scuff is how you make things worse.
- Shiny metal at the bottom, bigger than a pencil eraser? Do the touch-up soon. Bare metal rusts, and rust spreads under paint.
- Longer than your hand, or through to metal along the whole length? That's aerosol-or-body-shop territory. A brush can't make that invisible, and we'd rather tell you now.
What you need
- Touch-up paint mixed to your exact paint code — not "close enough" off a shelf. Your code is on a sticker in the driver's door jamb on most cars. Look it up here and we'll mix it fresh.
- Isopropyl alcohol and a clean microfiber cloth
- A toothpick or fine brush (our 2oz bottles have the brush built into the cap)
- Ten minutes of patience per layer — this is the one people skip
The process
- Wash the panel, then degrease the chip. Wipe the chip and the inch around it with isopropyl on a microfiber. Any wax or road film left in the chip stops paint sticking. This step is 30 seconds and skipping it causes half of all failures.
- If there's rust, deal with it first. Scrape the loose rust out with the tip of a toothpick or fine sandpaper. Paint over rust and the rust keeps going underneath — you'll be back in six months.
- Less paint than you think. Dab — don't brush — a thin layer into the chip. You're filling a hole, not painting a wall. The paint should sit below the surrounding surface after layer one.
- Wait. Then do it again. Give each layer 10–15 minutes. Two or three thin layers beat one thick blob every single time. A blob shrinks as it cures and leaves a crater with a ring around it — the classic bad touch-up look.
- Stop when it's level. Build the paint until it sits just proud of the surface, then leave it alone. Full cure takes 24–48 hours depending on temperature.
- Optional: polish. After a few days, a light polish blends the edges. If you used our 1K gloss touch-up, the gloss is already in the formula — no clearcoat step. Polish directly and you're done.
The three mistakes that make it worse
- One thick coat. It shrinks, wrinkles, or runs. Thin layers, always.
- Wrong color. "Black" is not a color — BMW alone has dozens of blacks. If the paint isn't mixed to your code, it will show in sunlight, guaranteed.
- Painting in the cold. Below about 50°F / 10°C, paint dries slowly, sags and traps moisture. Do it in the garage or wait for a warmer day.
Quick answers
How long does touch-up paint take to dry? Touch-dry in 15–30 minutes, safe to drive in an hour, fully cured in 24–48 hours.
Do I need clearcoat on top? With traditional basecoat touch-up, yes. With our 1K gloss formula, no — the gloss is built in, which removes the step most DIY jobs get wrong.
Will it be invisible? Honest answer: from a few feet away, yes. Nose-against-the-panel, a filled chip is a filled chip. Invisible-at-any-distance requires spraying and blending — which is a bigger job, and for one chip, rarely worth it.
