First time user of ceramic coats here and I cannot be happier with the result. It's very easy to use......just make sure you fully prep the car before applying. I used gyeon primer and gyeon prep prior to applying. The first coat I put on quite thick using a lot of the product, left for 30 sec to a minute before buffing off, I used all 4 applicator towels and 4 buffers. 50 ml bottle was plenty to apply 2 coats to a 2016 civic.
