1) USE MICROFIBER CLOTH TO LEVEL THE COATING
Using a microfiber cloth to level the coating can be of great help if you find the high spot soon, I.e.just after you apply. When the coating cures, it becomes hard, and after a span of time, the hardness can't be levelled with a microfiber cloth.
Cheap and quick way is to use vinegar to remove the spots. Another option is to use CarPro Iron X, which is safe on ceramic coating, but just note that it smells so so very bad. After removing the spots you can use CarPro Elixir or even CarPro Reload.
A high spot is a small area of excess ceramic coating that stands out from the rest of the surface. It looks like a tiny mountain or bumps on top of the surface of your car and can be a real eyesore.
Buffing your ceramic finish with a microfiber towel is the first step in reducing high spots. If the coating hasn't yet hardened, this will remedy the problem 99 percent of the time. Unfortunately, once the coating has dried, it becomes very hard to level with a microfiber cloth.
Applying ceramic coating correctly can help keep your car looking newer for longer. Mistakes can cause damage to the paint or even scratch it.
As mentioned before, some expensive packages consist of multiple layers of ceramic coating. However, for many of these packages, it is only a gimmick. Yes, you can put too much ceramic coating. After a certain point, further layers stop bonding and it is only a waste of material and overcharge to customers.
When water droplets evaporate, the minerals within the droplets remain on the surface, leading to the formation of spots. These spots can be particularly visible on ceramic coatings due to their hydrophobic nature, which causes water to bead up rather than spread evenly.
Dish soap will not remove ceramic coating, however, you should never use household detergents on your car.
Ceramic coatings form a solid, semi-permanent layer on top of the paint, which cannot be removed through conventional polishing methods. Polishing involves the use of abrasives to remove imperfections and restore the paint's gloss.
As a result, a ceramic-coated car maintains a cleaner appearance for longer periods, as contaminants are less likely to bond with the surface. By running your hand over the paint, you can assess the presence of a smooth and slick surface, indicating the likelihood of a ceramic coating.
It's best to apply ceramic coatings evenly in one or multiple thin layers using a self-lubricating applicator such as a foam brush or microfiber cloth. Begin by gently wiping the applicator in circular motions at a 15-20 degree angle from the surface, making sure not to re-insert it into the same area.
Because of its restorative properties, applying a polishing compound to your ceramic coating would simply strip away this protective layer, leaving your car with nothing but the exposed clear coat. While this is great for removing old layers of wax, it shortens rather than extends the life of your paint sealant.
To check for small high or low spots that may not even be visible, place a long level or straight pipe on the subfloor. Move it around to different areas and mark any high or low spots you find with a pencil or marker. Most floors will have at least some slight variations.
The lesson is simple: unless your goal is to strip the ceramic coating off your car, keep the polish away. Car wax and polish are not the same. Car waxes with ingredients like carnauba wax and synthetic shine polymers are perfectly safe to use—and even recommended to use—on top of ceramic coatings.
A ceramic coat layer, when applied correctly to a car's paint, can provide complete coverage in just two coats. Two ceramic coating layers plus a top coat layer are usually required. To maximize the hydrophobic properties of the ceramic coating, multiple layers are required.
However, when used by inexperienced car owners who don't know how to properly apply paint protection products, ceramic coatings can lead to issues like high spots, streaking, oily-looking finish, gritty textures, and poor coverage.
