Not in my case. I had some left-over Por-15 clear rust preventive that I wanted to use because of the limited time before the rest of the can cures.
So I cleaned up the outer fender wells of the front wheels with tolune, then acetone, then scratched it with sandpaper. Then applied the clear in 40degF temps. It stood a week before the roads..
That was 40k miles ago. It remains un-chipped and a simple water hose cleans it 90% worth. The A-frame with Por-15 black has some chips.
So I guess the stock fender well flex-undercoating aided the non-chipped Por clear......Ron
