I've had some peeling paint on the rear fender of my car since mid winter, took it to a car wash last week and it was kind enough to remove the loose paint for me.

How difficult is it to blend in on a panel like the rear wheel arch? I see that the paint inside the wheel well is also peeling.

Any advice or guides would be appreciated. I've done some body work before, but I didn't need to blend as it was a lower half of a door with plastic door guards running the width of the door.
