Rubbing clear coats.

I finished clear coating my car and I waited one week for the coat to dry up. Then I wet sanded it with 1500 grit and 2000 grit. Thinking all the surfaces were ready for rubbing, I rubbed it without problem except for the left front fender. It did not shine like all the other parts of the car. The fender glows dull and when touched by hand, it leaves hazy print marks on the surface. I did another round of rubbing it but the problem is still there. Can you help me what caused it and how can I fix it?

Is there a possibility you sanded off all the clear on that fender? That's what it sounds like to me.

sounds like he sanded into the basecoat to me too.

It's very hard to diagnose a problem without seeing it. So photos would help and would a step by step on how you painted the car.

Did you mix all you paint at the same time? or mix each cup before you shot it on the car?

Did you use a gravity feed gun and mix the clear in the cup and start on that fender? If so you have un-catalyzed clear on the first few passes of that fender.

Thanks for replying. My pad is clean and yes I'm using an electric buffer. It's a black and decker with variable speed - 1200 to 3000 rpm. I buffed the car at 1600 to 2000 rpm. I will appreciate any advice you can give me to correct the problem. Thanks.

If you can take a damp rag or a piece of 2000 grit and sand that spot. One pass will tell you if you blasted through the clear. If the residue is whitish, you should be safe(unless the paint is white), If the residue is body color, you blasted through the clear. Other than that, the post about uncatalyzed clear makes me wonder.
Good luck,
Chip.
