How to Polish Hard Paints Like Audi, BMW, and Mercedes
German clear coats are known for their durability — and their stubbornness. If you’ve ever tried polishing a BMW, Audi, or Mercedes and felt like nothing was happening, you’ve met hard paint. In this guide, we’ll break down how to safely and effectively polish hard paint systems using the right pads, speeds, and Picture Perfect Polish.

Why German Paints Are So Hard
Manufacturers like Audi, BMW, and Mercedes use ceramic-reinforced clear coats that are more resistant to scratching and chemical etching. This makes them durable — but also much tougher to correct. Regular polishes may barely make a dent in the defects without the right combination of pad, pressure, and patience.
Hard paints require more cut and working time, but when corrected properly, they deliver mirror-like gloss and incredible depth.
How to Identify Hard Paint
Not every car from these brands will have the same hardness. To determine if you’re dealing with a truly hard clear coat, perform a simple test spot:
- → If your polish barely removes light swirls, the paint is hard.
- → If you can’t mar it easily with a microfiber towel, it’s hard.
- → If even medium pads struggle to correct it, it’s definitely hard.
Pro Tip: Newer models with ceramic clear coats (especially Audi and Mercedes) are almost always on the harder end of the scale.
Tools and Products You’ll Need
- Polisher: Dual-action or forced rotation machine for control and power.
- Pad Selection: Start with a cutting foam or microfiber pad.
- Polish: Picture Perfect Polish — pad-dependent formula that adapts perfectly to hard clear coats.
- Lighting: High-CRI LED inspection light for accurate defect assessment.
- Microfiber Towels: Use quality towels to safely wipe off residue without marring.
Step-by-Step: How to Polish Hard Paint
- Prep the surface: Wash and decontaminate with a clay mitt to ensure a clean surface.
- Prime your pad: Lightly coat your pad with polish for consistent contact.
- Set your speed: Use speed 5–6 for correction and 3–4 for finishing.
- Apply firm, controlled pressure: Hard paint needs energy — don’t be afraid to press lightly while maintaining pad rotation.
- Work slowly: Move the polisher at about 1 inch per second for even results.
- Inspect frequently: Check progress after 3–4 passes to avoid unnecessary abrasion.
- Finish polish: Switch to a softer pad with the same polish to maximize gloss.

| Correction Stage | Pad Type | Speed Setting | Technique |
|---|---|---|---|
| Cutting | Microfiber or firm foam pad | 5–6 | Firm pressure, slow arm speed |
| Polishing | Medium foam pad | 4–5 | Medium pressure, cross-hatch pattern |
| Finishing | Soft foam pad | 3–4 | Light pressure, long slow passes |
Common Mistakes When Polishing Hard Paint
- → Using too soft a pad — you’ll get zero correction.
- → Moving too quickly — slow, overlapping passes are key.
- → Not cleaning pads — clogged pads can stop cutting entirely.
- → Skipping protection — hard paints still oxidize without ceramic sealing.
Protect That Perfect German Gloss
After correction, seal your paint with Tough As Shell ceramic spray for six months of hydrophobic protection and incredible slickness.

- → Use multiple pads per job to maintain consistent cut.
- → Warm up your polish slightly — it performs better on cool, dry panels.
- → Don’t overwork the product; wipe off once it turns clear.
- → Always follow up correction with a coating or spray sealant.
- → If defects won’t budge after several passes, step up your pad before changing polish.

FAQs
Why is German paint so hard to polish?
It’s reinforced with ceramic particles that increase durability and resistance to scratching — but also make correction slower.
What pad works best on hard paint?
A microfiber or firm foam pad provides the cut you need while maintaining control and reducing heat buildup.
Can I finish with the same polish I cut with?
Yes — Picture Perfect Polish is pad-dependent, so switching to a softer pad transforms it into a perfect finishing polish.
Is hard paint harder to damage?
It’s more resistant to light scratches, but once it’s damaged, correction takes longer and more effort.
What’s the best way to protect hard paint after polishing?
Seal it with Tough As Shell ceramic spray or The Gloss Boss coating to maintain shine and prevent future oxidation.
