Here's a brief tutorial:
Ok..get your materials in order. Masking tape, 2000, 2500, 3000 grit sandpaper, bucket of water, PlastX polish and microfiber cloths
Mask off around the light. If you slip and sand your paint, you'll hate yourself.
Soak the paper for at least 15 minutes. The more water the merrier! Using the lowest grit, start sanding in ONE DIRECTION ONLY,(side to side). Keep the sandpaper wet and dip it in your bucket of water frequently! Dry it off, and admire how bad it looks now!. Don't panic..we're not done yet!
Switch to the next finer grit, and repeat the step above, but this time go in the OPPOSITE DIRECTION (up and down). Remember, water is our friend!
Dry it again, and you can see it looks better as we go up in grit.
Repeat the process again with your finest grit. Again, OPPOSITE DIRECTION with plenty of water. Dry it off. It looks pretty good at this point. You can choose to remove the tape, since it will have some grit and debris on it from the sanding. You don't want this grit to contaminate the final polishing process.
Generously apply the PlastX. Don't skimp. I prefer using a cloth instead of my bare hand.
Using your microfiber cloth, rub off .. repeat several times with FRESH rags until the PlastX is dry and gone. Be sure to polish until it's dry, since PlastX has diminishing abrasives in it.
