Here are the details. I did mine by hand as opposed to using a buffer. I didn't remove the headlights..just used painter's tape to protect the other areas. I had to purchase 3 different packets of sandpaper (auto parts store) because they didn't have a multipack. I spent about $25.00 total, but it was well worth it considering the fact that a new headlight runs close to 300.00!!

Tools needed:
800 grit sand paper
1000 grit sand paper
1500 grit sand paper
Some sort of wet-sanding liquid (water, instant detailer, a light degreaser)
Cutting Compound of your choice Polishing Compound of your choice
Optional tools:
Machine buffer, Rotary, or DA with pads (I used a PC7424 with 2 different levels of CCS pads)... Power tools will cut down on work time/effort required by exponential amounts
Various assortments of Torque (T25, T27) if you will be removing the headlights/bumper-cover
Some sort of paper-tape if not removing the headlights/bumper-cover
Step one:
If removing the headlight is not an option, be sure to tape around the lens to protect the paint on the vehicle (we will be sanding). Save yourself some time and effort by taking this step
Step Two:
Begin wetsanding the headlights using the most course grit first (I started with 1000 grit but 800 grit would have been better). Be sure to go in a back in forth or up and down motion, DO NOT MAKE CIRCLES!
Step Three:
Progressively move towards a finer grit of sand paper until you've reached the finest grit you have (I finished with 1500). The headlights will begin to haze over. DO NOT BE ALARMED, this is good. We will buff that out later
Step Four:
Use a rubbing compound to slim down on the scratches/haze that have developed as a result of wetsanding. Again, go back and forth, DO NOT MAKE CIRCLES. (I used a PC7424 with Lake Country CCS pads (yellow and orange) and Pinnacle XMT#4)
Step Five:
Use a polishing compound to get the finished look. (I used the PC7424 with a Lake Country White CCS and 3M Finnesse-IT2 Finishing Polish)
Hope this helps...
