There are a lot of methods used out there but I stick with what I know works.
Rotary Buffer
1st round is Meguair's 105 and a twisted wool pad.
Work a 2'x2' area or smaller at a time and run the buffer at 1000 - 1500 rpms to work the compound in and then up the rpms to 2000 - 2500 and buff the section. This will remove all haze and any scratches less than 1200 grit. The surface will/should look real nice after this.

2nd round is Meguair's 205 and a foam pad light cutting pad.
Same procedure except the rpms can stay in the 1500 range. This will remove 90% of the swirl marks and the panel should look nearly perfect when done.

3rd round is Menzerna Final Finish 3800 on a foam polishing pad.
Same procedure as round #2 but this stuff will remove the micro-scratches that only show up in sunlight.

Im having helluva time buffing this car out. Sanded all the way out with 3000 and Megs 105/205 combo and Feracla G3 isnt working worth a flip. This is only the 2nd car Ive done but the Distinctive Image clear seems to be a lot harder to deal with than PPG.

Get a twisted wool pad for the first go around. I have tried all the foam pads and they just don't cut like twisted wool.

Today's clears are much harder IMHO and the feared swirl marks from the wool pads are non-existent. One time over a panel with twisted wool and Megs 105 will make a believer out of you.

When you get better at spraying clear coat, you can start with 2000 grit like Dave does and then maybe foam pads will be enough. However, for most of us part timers and hobbyists who want to correct the flaws the 1000 - 1500 - 2000, etc. route is the best IMHO.

The pictures I post are proof this method works. I have more pictures if you feel you need convincing.

One side is done. I will go back and try the twisted wool. Just makes me nervous as I already burned through the trunk with the wool and had to repaint.

twisted wool arent bad to use once learned.
personally, when i started using them, i started out with slower rpms, let the buffer do the work- no downforce, never let it sit in one area, and stop occasionally and lay the back of my hand on the surface to feel the temp of the surface.
i gradually worked up the rpm's the same way,stopping occasionally to feel the surface with the back of my hand. now, i might be able to buff longer, but ill stop when the area feels warm to the back of my hand then either move to another section and work it,then come back or just let it cool down.

the directions for M105 say work at MAX 1500-2000 rpms, but i dont think im up that high on rpm's.

imo, its better to start with lower rpm's and work up then starting with higher and workin down.
guess how i learned that! :shocked:
