Just did my whole car in Armor Shield ceramic coating. Took about 4 hours total time, but my car was not super dirty. Did the windows and mirrors as well as the wheels.
It is very easy to apply, so it’s sitting in the garage for 24 hours to let it bond to the paint. The one thing I noticed is my paint had a couple of spots that were touched up. I don’t know if it came that way off the boat or someone touched it up as my car was a demo.
Also found 2 scratches that did not know existed. Have no idea if they were there when I bought it. Luckily I have a buffer wheel and got 90% of it out.
Hopefully this stuff works as advertised.
