I do a LOT of car detailing.
1) First thing you want to do is wash the car.
I recommend using Meguiar's Wash and Wax [LINK]
2) Second is inspect the surface. Feel the car and if seems gritty you'll need to clay bar it.
I recommend using Meguiar's Smooth Surface Clay Kit [LINK]
3) Third is inspect the surface for oxidation/fine scratches/swirls/scuffs. If so, use a rubbing compound.
I recommend using Meguiar's Ultimate Compound [LINK]
TIP: This works best with a DA Buffer/Polisher. Works well with hands application but for best results using a buffer is ideal.
4) Forth, if everything looks good it's time to polish.
I recommend using Meguiar's Ultimate Polish [LINK]
5) Fifth is waxing the vehicle. You have 3 options when it comes to wax. Paste, Liquid, and Spray. Personally I recommend Paste Wax as I feel it covers the vehicle better but Liquid wax is still great. Spray wax is used for "Quick" applications in-between normal wax/washing.
For Paste Wax I recommend using Meguiar's Ultimate Paste Wax [LINK]
For Liquid Wax I recommend using Meguiar's Ultimate Liquid Wax [LINK]
For Spray Wax I recommend using Meguiar's Ultimate Quik Wax [LINK]
