I was underwhelmed by my current newish car's paint sealant. It was nice that I didn't have to wax it for the first few years, but I am surprised that it's only been 4 years, I have had the paint sealed twice and yet the bugs have burned their way into the front paint. I am going to cover the front with 3M film. I have read that the films are great for bugs and rocks, but terrible for bird poop. I may just do the ceramic opticoat stuff on top of the film and the rest of the car. I do like how easy it is to clean a car that has paint sealant. Just wish it would keep the swirls out of the paint...
