i've done that kind of amazing stuff too. i used to own a detail shop, so i got a bunch of crap in like that. in fact i just did my 93 jeep last week that i haven't even washed in almost 2 years, looks better than the day i got it and it had a repaint shortly before i got it too.
the trick is to do it in steps. heaviest compund to lightest compound, glaze, the wax. i use 2 different waxes, first carnuaba wax then i follow that with a sealer wax.
on some cars you may find that it will need to be color sanded and the buffed, especially on really oxidized metaliics. this step is the worst by far. use the lightest grit paper you can to get the job done. i usually use around 1500 grit to start and adjust from there.
it doesn't look like your car will need to be color sanded or even need a very heavy compound, in fact you might able to do it with just a glaze, then wax it really good.
