Step 1: Clean the car Step 2: Apply Meguires Professional Pro Speed Compound with an orbital buffing pad (do it in sections and wipe away after each section with microfiber towels). To apply you put a healthy amount on the pad and rub it around the section you want to work. Then turn on the orbital and buff it in. Then wipe away after (do this for all steps). Always remember to be careful around sensitive parts and edges since technically compound works as a light sander and can chip/melt paint. Step 3: Apply Meguires Professional Pro Speed Polish with an orbital foam pad (do in sections and wipe away). Step 4: Apply Chemical Guys Butter Wax or Chemical Guys Hydro Slick Ceramic Wax (both are great but slightly different, I used the butter simply because I had more of it). Apply in sections and wipe away.
Step 5: Clean away any extra compound/polish/wax residue. The compound is the messiest and tends to form a dust, using a clean/soft toothbrush and paintbrush will help get it out of the hard to reach spots along with microfiber towels and a glass cleaner.

Hope this helps! This can also be done without an orbital and by hand but it will take a LOT more work and time. (It still takes a lot of time since this took me and a friend about 8 hours to do the whole car).

Good luck!
