Here’s an alternative that worked for me.
Bought my SPF new in 2009. After 12,000 miles, the front end paint looked like it had gone through a sand blaster. Only driven on Southern California paved roads and freeways. Chips all over the front of the car.
Got into a minor altercation with a cement flower stand and had the front half of the car repainted. The painter applied more clear coat this time.
Now, after another 15,000 miles on the same roads, there isn’t a single chip on the front end.
Maybe a good clear coat is the answer.
