'72 Dart original paint

Start buy claying the paint, Just use soap and water, No need for the spray they try to sell you with it. Lots of suds, wash and clay a panel at a time.

I would use the D/A with a yellow foam pad and some Maquires 205 polish to start speed on 4, then switch to a black foam pad, same polish, speed on 3. Finish with a good wax, blue foam pad, speed on 2.

You can also use a good paint sealant if you wish, apply it with the blue pad, let it haze for about 20 minutes then wipe it off. Let it sit 24hrs before topping the sealant with wax.
