303 should work just fine
 
Sorry if I have missed it in the thread (did a quick 'Search in this thread') but what do you do (if anything) about providing UV protection after sanding/polishing on the lenses?



Edit: Is that what the Polycharged UPP is? Or is that a wax/sealant?
 
Here are two pics of the lights I'm talking about. The first pic is the one I've been working on. Wet sanded with 600, 1500, then 2000. Used Meguiar's #10 & #17 after, but you can still see way too many fine scratches. The second one I have not started yet, just a reference point to show what the first one looked like before I started. I think I'll need to go with a finer sandpaper to get these clear again. Any suggestions? Thanks.

On plastics you definitely need to sand down to a finer grit. You are wetsanding right?



Once you get the plastic looking like a sort of.. glazed over cloudiness, then you can hit it with PlastX or any other compound/polish and get it looking close to brand new.
 
You have to be absolutely sure that you remove the sanding marks from the courser grit with the finer grit or the end result will be what you have now. You basically will have to spend a lot of time with the 1500 to make sure you removed the 600 scratches and then make your way to 3000 or so. Plastic doesn't polish up all that well when deeper scratches remain.
 
Sanding the plastic is difficult, especially with the more harsh grit papers, because you need to keep your pressure as even as possible.



It is really important to get some nice sanding blocks to make sure that your pressure is even.



Also remember that with the plastic, the sanding is doing almost all of the finish work, not the polisher. It is different than with sanding and polishing a clear coat.



So really focus on taking your time and making it as perfect as you can with the sandpaper before turning to the polish to take out the really fine scratches.
 
Wow, did someone try to clean his headlights with scratch pads or what? That is pitiful... I bet he could barely see at night.
