PTG arrived yesterday so I took measurements on the decklid before doing any work, after OP removal and after polishing with Menz 2500. Here are some pics of that work:
Before:
I did switch to a rotary and tried two different setups. One was after watching Osren products, they load up their pad with compound and go after it. That seemed to work, at first, but the pad would gum up very quickly. I switched back to super small, like smaller than a pea sized drops. That was much easier to control.
Here is during, you can see the OP based on how the compound was "missing" in spots:
After leveling:
After shots, this is polished with Menz 2500 on a white hybrid:
You can see the wear line from the spoiler, I pulled it off to allow me to get to all the paint on the lid.
Most measurements along the trunk were 5.5 to 5.6, after leveling and polish I saw a .2-.3 drop in thickness.
