There are two common types of ceramic coatings, a kind for professional use only where you need to make a professional paint preparation before applying; this type will last longer, with more durability, a better glossy effect and super-hydrophobic coating.
The other type is what you could call a DIY product, which provides less thickness but can still achieve good quality with a glossy effect, slickness, and super-hydrophobic coating.
In any case, if applying a ceramic coating, you should wear suitable protective gloves, masks and goggles, and work in an area with good ventilation. For professional ceramic coating products, it's advisable to visit a professional detailing shop to get the best results.
Some points to consider when choosing a ceramic coating product would include:
1- Choose between Sio2 (Normal Ceramic) or Graphene Spray; Graphene Coating is the best available product available these days.
2- The durability of ceramic coating is better than wax and sealant, and it will last longer, check how long the ceramic will last and is it possible to be maintained.
3- Be aware that ceramic coating might damage the paint if it is not applied correctly.
4- Ceramic coating can vary in thickness, slickness, gloss effect and hydrophobicity; check the thickness of the coating and look for the correct hardness and hydrophobic angle.
5- DIY ceramic coating products are less thick but still provide a good result, so this is a good option for small detailers and car owners.
6- Always look at the application instructions. Is the product easy to apply and safe to apply outdoors under direct sun, or only indoors? And what is the best temperature and humidity to make the application?
7- Des the product need preparation before application and are you able to do this preparation? Many products need professional preparation, while others are easy to use and need only need spray and wipe.
8- Check the product's maintenance requirements; as a rule of thumb, ceramic coating products need quarterly maintenance while high durable products will need to be maintained yearly. Maintenance will help refresh the coat and keep your car looking amazing.
9- The curing time of the product is very important since all ceramic coating types need time to cure and be 100% durable. Usually, this takes 10 to 14 days, but top-quality ceramic coating products will cure within 48 to 72 hours only and allow dry drive.
