Yea, the ceramic coating for paint is great. I have it on all three of our cars.
I "have a guy" that is local and does it in his home garage, and is very meticulous. He does a full paint cleaning with a clay bar, then a top coat of the ceramic. It has been 2 years since the cars were done.
When I drove down to Key West my first night was a stop 900 miles from home at my brother's house in Montgomery, AL. When I was in Mississippi I drove through some heavy rain, and that washed off all the bugs. My brother's first question to me was did I stop and wash the car when I got to town. I of course replied no.
Bugs and dirt do wash off easily. Of course the 911 and the El Camino are both single stage paint. The Wife's 2017 Macan is two stage paint, and we put the clear bra on the front of it. The ceramic goes right over the clear bra. You can't see the finish, except the gloss is a little higher than just wax.
The problem is that wherever I park it, chicks like this just gather to admire it.
