For detailing the interior, I find that a round horse hair brush works great for cleaning vents and cracks, etc. Then vaccuum it all out at the same time. I use the full Lexol leather package for cleaning and treating leather. Don't use anything too abrassive.
I like the 3M products for the exterior paint work. I used buffing compound followed by the required swirl remover, then protect it all with some hand-applied wax. I used an orbital variable buffer with a soft foam pad for the buffing. I also used the buffer to shine up the headlight covers using the Meguiar's cleaner and polish. I was speachless at how well that worked! Highly recommended. Don't bother trying it by hand, you will get nowhere. The headlights looked clear-as-glass when I was done, and this car has over 162,000 miles. In fact, they were so pitted/foggy before, I nearly replaced them.
Here's some photo's of the before, during, and after process:
It's a lot work,

but well worth it in the end.
