bring back faded paint...

[WRS]

how do i bring back faded paint? because one side of my car, the roof, and the trunk are all original paint and fading pretty bad. i don't how much time it takes to do this because my buddy said he'll let me use his garage so i can stay out of the sun as long as i do his 280Z which is faded all over. while at shuck's today i saw a Meguiar's 3-step process but i wanted to get some other opinions seeing as how i know nothing about paint restoration and all what not. also how do you get swirl marks out of the clear coat? may be a noob question but i gotta ask because they are really getting on my nerves.

thanks much...
