Ceramic coatings and touchless washes

A coated car still gets dirty

A ceramic coating is a hard, thin layer bonded to the clear coat. It makes the surface slick, so water beads and dirt lets go more easily, and it resists some chemical staining. It does not stop the car getting dirty. Road film, brake dust, salt and bird droppings still land on it, and if they're left there, they dull the coating and can etch into it.

The biggest difference you'll notice is that washing is faster and the car stays cleaner for longer between washes. It still needs them. A coating that's covered in grime also stops beading, which makes people think it's failed when it just needs washing.

Why contact is the enemy

Coatings are harder than clear coat but still wear. The main thing that wears them down is abrasion: dirty mitts, drying towels dragged across grit, and brush washes. Each pass takes a little off. A touchless wash uses shampoo and high-pressure water instead of contact, so nothing rubs the surface.

Touchless washes do rely more on cleaning chemistry to lift dirt without scrubbing. Most consumer coatings are designed to cope with regular washing, but products differ. That's the reason to ask the question below rather than assume.

Ask your installer three things

If a shop applied the coating, it likely came with care instructions, and some warranties have conditions attached. Check before you choose a wash routine, so you don't void anything by accident.

• How long after application before the first wash
• Whether automatic touchless washes are fine for this product
• Whether the warranty needs regular maintenance visits or a log of washes

The first weeks

Fresh coatings need time to cure fully, and installers usually ask you to keep the car dry and unwashed for a set number of days. Follow their figure, not a general rule from the internet, because it depends on the product. Bird droppings and tree sap during that window should be gently lifted with water and a soft cloth as soon as you see them.

About spray-on protectants

Many washes offer a protectant or shine product as an add-on. On coated paint, these sit on top of the coating rather than replacing it. Some coating owners like the extra slickness. Others prefer to keep only the coating on the paint, because a topper can change how water beads for a while and make it harder to judge the coating's own condition.

There's no wrong answer, but it explains why a straightforward wash suits a lot of coated cars. At Fast Lane, the Full Wash covers an under-car spray, shampoo wash, high-pressure rinse and dry, with no extra protectant layer, while the Luxury Wash adds Tri Foam conditioner and Shine Guard Plus if you want them.

Winter with a coating

A coating helps salt rinse off the paint, but it does nothing for the underside, which isn't coated. In winter, keep washing every week or two with an underbody spray, the same as you would with an uncoated car.
