I'm doin the whole 3 step wax thing with the Meguiers, first the scratch remover then the polish and finally the wax. Now the car is a '93 Acura Integra 2door. Anyways, the car had a bra on it for the longest time and now that I have taken it off there black residue stuff left over from the edges of the bra and its hard to get off mostly. Though I can get most off with my finger nail, lol. Also a lot of sap had fallen on the car and I did my best get it off but it has seem to stain the paint on the spoiler and a few other parts. Then on the roof there is a spot that the paint has faded a bit. And finally on the lower part of the car on the doors and fenders it seems really oxidized or something, the paint looks kinda fogy. What can I do to fix anyone or all of the things.

You may want to start by washing your car with Dawn, the Dawn is stronger (only slightly) than normal car washes, then clay the car, the clay will remove sap and other contaminates, then rewash and start your Meguiar's 3 step system. If you have a lot of oxidation you may want to start first with a product like 3M Scratch and Swirl Remover, it's best when applied with a buffer but can be used by hand. The paint fading can not be fixed without repainting, but the other problems should be no problem.
