Door cups might be the smallest correction job with the biggest payoff
MD Car Care tackles those little fingernail scratches behind the door handle with nothing more than 3D SPEED and a microfiber towel!
No machine needed.
SPEED can be worked by hand for localized light correction, which makes tight areas like this a perfect use case. A small amount gives you enough abrasive action to improve light scratches and haze while also leaving behind wax protection.
Pro tips:
→ Check the scratch before promising removal. If it’s only in the upper clear coat, you have a good chance of improving or removing it. If your fingernail catches hard, set expectations accordingly.
→ Tight areas reward patience. Work a small amount of product into the defect with controlled pressure rather than flooding the area with polish.
→ Wipe clean and inspect from multiple angles before doing another round. You want to know whether you’re still correcting a defect or just removing more clear coat chasing something too deep to safely eliminate.
And make sure you’re working on a painted/glossy surface, not textured unpainted trim.
Save this one for the next customer whose door handles tell you exactly how they open their car every day. 😅
