A chip down to bare metal will rust in 2–6 weeks depending on humidity. Once rust starts, the only fix is body filler, primer, and paint, which is a 4-hour repair. Touch-up paint applied today is a 30 minute repair that stops corrosion in its tracks.

⚠ When NOT to DIY thisIf the chip is already rusty (brown or orange), stop. Touch-up paint over rust looks fine for 30 days and then bubbles. You need to grind out the rust with a wire wheel and re-prime first, or take it to a body shop for $80–$200 per chip.
📝 Step-by-Step Instructions
- Find your paint codeOpen the driver door, look for a sticker on the door jamb with a 3–4 character paint code. Order touch-up paint matched to that exact code. "Color name" is not enough - manufacturers use 4–7 codes per color.
- Wash and degrease the chipHand-wash the area, then wipe with isopropyl alcohol. Any wax or polish residue will prevent paint from bonding.
- Inspect under magnificationLook for any micro-rust spots in the chip. If totally clean and silver/grey, proceed. If brown - go to the warning section.
- Apply paint with a toothpick, not the brushThe brush in the touch-up bottle applies way too much paint. Dip a toothpick tip into the paint, transfer one tiny drop into the chip. Repeat to fill the chip from the bottom up.
- Let each layer dry 1–2 hoursMost chips need 3–6 thin layers. Rushing creates a thick blob that will look raised and obvious. Patience is the only thing separating a great repair from an awful one.
- Fill slightly above the surrounding paintWhen you stop adding layers, the touch-up should sit a hair PROUD of the surrounding surface. It shrinks slightly while curing.
- Apply clear coat once color is fully curedAfter 24 hours, dab a layer of clear coat with a fresh toothpick. This is what makes the repair glossy and blend in. Without it, the spot will look flat and dull.
- Wait 48 hours, then level with rubbing compoundApply compound on a microfiber, rub gently in a circle. This levels the high spot down to match the surrounding paint and feathers the edge. Don't overdo it - check every 30 seconds.
- Wax or seal the area to protectA fresh repair has no UV protection beyond the clear coat. Add wax or sealant for long term durability.
💡 Before & After Tips
Use a toothpick, never the bottle brushThe single biggest reason DIY chip repairs look bad is using the brush that comes in the bottle. It dumps 10x more paint than you need.
For chips smaller than a pencil tipDon't bother with clear coat - just one drop of color paint. Tiny chips don't need leveling.
Repair in shade at 60–80FDirect sun makes the paint flash too fast and leaves brush marks. Cold weather (below 50F) prevents proper curing.

❓ Frequently Asked Questions
How long does touch-up paint last?
5–10 years if applied right and the clear coat is sealed. Without clear coat over the top, expect 1–2 years before it dulls and flakes.
Can I use nail polish instead of touch-up paint?
Only in an absolute emergency. Nail polish is a temporary spot fix at best - it doesn't bond properly to automotive clear coat and will yellow within months.
What if I can't find my paint code?
It's usually on the door jamb sticker, but it can also be on the firewall, glove box, or trunk. If lost, call the dealer with your VIN and they can look it up in 60 seconds.
How do I fix a chip the size of a dime?
Larger chips need primer first, then color, then clear. AutomotiveTouchup and Dr. ColorChip sell kits with primer + color + clear matched to your code.
Will rubbing compound damage my paint?
No, when used gently with light pressure. It's designed to level small high spots. Don't use it on the entire car, only on the repair area.
Should I just wait and let the body shop fix it?
No. Every week you wait increases the chance of rust. A $30 touch-up today saves a $400 panel repaint in 6 months when the rust bubbles spread.
