So I did the second coat this weekend.
My car was really dirty and I had a fairly open Saturday, so I decided to give the car a full decon wash and pulled out the bottle of left over Pure Evo.
I started with the trunk lid and thought it looked pretty good after it sat for a little bit, so I decided to do the whole car.
To be very honest, on the bright blue pearl paint, I'm not sure I notice much difference between one coat and two. I might have added a bit more gloss and depth, but in my eyes, it's minimal. One layer looked amazing, so I'm not sure what I thought I'd gain from a second.
If anyone is going to try thing I highly recommend doing the second coat as soon as possible after the first. Don't wait months like I did. Applying the coating wasn't hard and it seemed to go on much like the first application despite coming out of a bottle that was opened this spring. Where I ran into issues was the removal. I'm not sure if it was because the coating is aging after being opened, there was remnants of something on my paint I didn't totally remove like Gyeon Ceramic detailer I used a month ago, or something environmental, but I noticed after buffing a haze started to form. This has was NOT present when I did the first application and I could remove it despite it being a bit grabby. Getting the right lighting to see it was a real treat, but it could be removed after some time and effort.
