Bah!
Forget the clear coat!
Jsut get about 4L of really really strong paint stripper and water blaster.
Paint the car with the stripper, leave it for an hour or two, and blast all the paint off.
Dry the car really well then just poor used oil all over it to stop it going rusty!
You might need to reoil it evey couple of weeks, but think of the nice shine! and NO one will ever sit on your car in the parking space ever agian.
