 I just bought this car, and the car was sitting around and the bottom of the car was surrounded by grass, and the bottom part of the car's paint is almost new, cause the sun messed up the paint on top, the paint is on but not shiny and when you touch the top part of the car, your hands get full of paint, do you think that if I spray the car with clear, maybe the this could fix the paint, or look better, let me know your opinion, and if it's possible let me know how to prepare the paint, for clear.

Answer -
Doug,you are opening a can of problems if you try to clear the car.The best bet is to buff and polish the existing paint.The paint on your car is a single stage and does not have a clear.The shine will last for a few months if properly maintained and kept out of the sun for extended periods of time.In the long run you will want to refinish the car with a basecoat/clearcoat finish.

Answer
Doug,up untill the late 80`s most car manufacturers didn`t apply a clear at all.They would use an enamel or laquer paint that didn`t require a clear.How the paint came out of the gun is how it looked.A little buffing to remove dirt or other imperfections was all you might have to do.Living in a hot climate will cause the paint to 'oxidize'faster,the heat causes the outer layer of the paint to open up and allow oxygen into the finish which causes the milky appearance.Buffing heats the paint and allows the oxygen to get out to restore the original shine.Waxing the car keeps a protective barrier on the paint to prevent this.If you keep a quality car cover on, the finish should last a while if it is not too far gone already.Too much buffing eventually takes off layers of paint and you will be forced to repaint anyway.
