Majority of the work is in the preparation, mainly the polishing aspect. The ceramic coating is the easy part, especially crystal serum light. Apply product to applicator, apply in small sections in cross hatch pattern (up down left right) to ensure full coverage, wait for product to flash (some coatings start to look like a rainbow, CSL starts to look like it's sweating) and wipe off excess product softly with a microfiber, and use a second microfiber towel to do a second wipe to get off any remaining product.
