I just finished detailing this red/maroon Sebring convertible. The condition wasn't as bad as other old cars. It only had some minor swirl marks from every day use. There were other deeper scratches present as well. First I washed the car and wheels using Turtle Wax ICE Car wash via Gilmour Foam Gun. I also used APC+ to scrub the tires and the wheel wells. Here are some pictures after washing the car:
I then clayed the car and here are some pictures while and after doing it.
