If I remember correctly there was a 3 month problem with there being bad primer put on the hoods of our cars when built. Mine fell in the time period. I too had excessive amount of rock chips. When I had the front of mine repainted I told them of the primer problem and it was a lot more than the stated $900.00. Since then I have just driven slower.
When I travel on the interstate now I stay right around 60 mph. This gives the rocks and bugs time to get out of the way. LOL
So far so good. It has been about a year since repaint. No chips.
I wouldn't put the clear protective film on my car even if it was free.
