Before switching to another grit, check the dome closely and inspect for the Scratch-pattern left by the sandpaper. It should be uniform. The finer grit you'll go, the less apparent the scratches will be, Although it's not possible to perfectly polish polycarbonate, with the proper method and finishing compound, it will look good enough.
Sometime, to really see if the sanding is well done, rinse the dome, dry it with a soft cloth, and check a ceiling light through it. A wet dome always look somewhat better than dry, thus making you think it's well sanded when it's actually not. You will also spot more easily any remaining scratches on a dry dome. When all scratches are removed, it's only a matter of elbow oil to gradually sand the dome grit by grit.
After 2000 wet-or-Dry sandpaper, I use this:
Micro-Mesh Finishing Kit
MeguiarsDirect.com: PlastX Clear Plastic Cleaner & Polish using this: Mothers® PowerBall Mini®
I finish with Turtle Wax Platinum car wax.
Here's the results I got with this method.
Again, it DOES take a while to achieve this method.
Good luck; I hope this helps!

I used a micro fiber clothe with some megguires plast-X head light restore....looks pretty good, I think I will soak them in hot soapy water to give a good cleaning then follow up with another application of the plast-X

I just used a spray bottle. Do it somewhere where you won't care if you make a mess.

My next question to this technique.
I have polished my headlights with the Mequires kit. It lasted about a year and a half, and now they are just as yellowed as before I did it. What do you do to prevent the domes from hazing again, or for that matter, the headlight lenses from going back to what they look like before??

Comparison photo. Used the 3M kit. Worked great I think. Once I got the routine down it took no time at all to do.
ETA: Sorry it's upside down. I'm not smart enough to figure out how to fix it. You still get the point though.

Which way is best
Which way is best when sanding out scratchs?
Going with the scratch or across it?
If going across then going the length of the dome?Sorry don't take Paypal/exceptions USPS money orders or cash or Walmart #5240 transfers ONLY.
