I finally DIY ceramic coated my car since the weather was nice. It sure is slick and shiny now. The large bottle of CarPro CQuartz (50ml) did 2 coats on the car and a car on the wheels. I have PPF on the front and did not need to polish that area but it still took forever I would have used a more aggressive polish because at night with fluorescent lights I can still see some micro swirls, but you can't see them in the daylight. I was aware this might be an issue but decided to just double polish and go for it anyways. This is my daily driver not a show car, but a more aggressive polish would have done a bit better. I used this polish: https://www.amazon.com/Meguiars-Mirror-Glaze-Swirl-Remover/dp/B0002SQVX0/ref=sr_1_3?keywords=meguires+swirl+remover&qid=1560188393&s=gateway&sr=8-3 I would have gone for this one next time (It was sold out at wallmart which is the local place that carries these: https://www.amazon.com/Meguiars-Mirror-Glaze-Finishing-Polish/dp/B001O7PNXC/ref=sr_1_1?keywords=meguires+polish&qid=1560188499&s=gateway&sr=8-1 My Process was: 1) Iron-X (applied to slighly dirty car (washed it one week ago, youtube tips say this helps it to stick and not run). 2) Foam cannon and wash, and rinse and dry. 3) Claybar 4) I did an ONR detail spray mixture wipe down instead of another wash. 5) used a random orbital to polish the car. (most time consuming part) 6) foam, wash, dry. 7) Carpro Eraser Wipe down. 8) One coat of ceramic, I hope I did this right. I would work a small area but it was hard to see it flashing on white paint. So I was sure to wipe it off before it dried. 9) Next morning I put on another coat of ceramic, and also applied the left overs to the wheels. 10) Next morning I put on the bottle of reloaded.
