GG 3" Orbital polisher for headlights question

[MoparAddict]

So i have a couple headlight jobs coming up this sunday. I normally use my 3" pneumatic polisher but my air compressor took a dump on me today and my electric drill has disappeared. I just recieved my new GG 3" orbital in the mail today, what speed do you recommended for sanding headlights? I use the 3M hookit sanding disc's, incase that matters.
Any help would be appreciated.
Thanks,
Trevor

I find everything but speed 6 is useless. Mark your backing plate to make sure it's rotating. I use my GG3 for headlights, and 6 is where it's at!

Perfect, I'll def mark my backing plate. Thank you for your help! I'll have to post some pics afterwards. They are some nasty headlights.
