Keeping Your Black Paint Mirror-Finish (Without Going Mad)

Never, ever wash a black car in direct sunlight. The water will evaporate in seconds, leaving nasty mineral spots that are a nightmare to remove. If you don't have a carport, do it at 7am or after 5pm.

Clean your wheels and tyres first. If you do them last, you'll splash dirty brake dust water all over your clean paint. I use a dedicated acid-free wheel cleaner like P21S or Bowden's Wheely Clean.

Cover the dry car in a thick layer of snow foam. Let it dwell for 5-8 minutes (don't let it dry!). This softens the dirt and 'lifts' it off the surface. Rinse it thoroughly from the bottom up, then top down.

Spray an iron fallout remover (like Gyeon Iron) over the paint. On a black car, you won't see the 'bleeding' purple as easily, but it's working. This dissolves those tiny metal particles from brakes and railways.

Wash one panel at a time using the two-bucket method. Dunk the mitt in the soap, wipe the panel lightly (no pressure!), then rinse the mitt in the plain water bucket to drop the dirt before going back for more soap.

If you've got a leaf blower or a dedicated car dryer, use it. Getting water out of the mirrors and badges prevents those annoying runs later. If not, use a plush drying towel and 'blot' the water off. Avoid dragging the towel across the paint.

Use blue painter's tape to cover plastic trim, rubber seals, and badges. Trust me, getting white polish residue off black plastic trim is a job I wouldn't wish on my worst enemy.

Don't just tackle the whole car. Pick a 40x40cm square on the bonnet. Start with your least aggressive polish and pad combo. If that clears the swirls, that's your 'recipe' for the rest of the car.

Put 4-5 pea-sized dots of polish on your foam pad. Dab it around your work area before turning the machine on so you don't sling polish all over the garage.

Move the DA polisher in a slow, overlapping grid pattern. Horizontal passes, then vertical. Keep the pad flat! If you tilt it, you'll create 'holograms' which look like greasy smears in the sun.

Wipe the area with a fresh microfibre and an IPA spray. Use a high-lumen torch (or your phone light) to inspect. Are the swirls gone? If so, move to the next section. If not, you might need a slightly heavier compound.

If you used a heavy compound to fix deep scratches, you'll likely need to follow up with a 'jewelling' or finishing polish on a soft pad to get that true mirror-like depth.

Once the whole car is polished, do a final IPA wipe to ensure every bit of oil is gone. The paint should feel 'squeaky' clean. This is vital for the coating to bond.

I reckon ceramic coatings are the only way to go for black cars now. Apply the coating in small sections. Wait for it to 'flash' (it'll look like rainbows or beads of sweat) then buff it off gently with two different towels, one to remove the bulk, one for final leveling.

Keep the car out of the rain and sun for at least 12-24 hours. Don't wash it with soap for a week. Let that coating harden up properly.
