On a severe swirl job I used Yellow LC pads and wore two of them down flat with very little results.
Then I tried the Surbuf pad with Meg105 and here are some thoughts...
This process can be messy.
1. Do not prime the surbuf pad.
2. Apply 4 "larger then pea sized" dots of M105 to the pad.
3. Work the polish into an 12x12" area without turning on your PC.
4. Spritz the surface with water.
5. As in step 3, again work the polish around without turning on your PC, you are looking for a milky consistency.
6. Turn on PC and work the polish till it appears to dry.
7. Spritz more water onto the suface and continue to polish.
....(What this does is bring the polish out of the pad and back to the surface)
8. I have found that you will need IPA sprayed onto your MF to remove the M105 from the surface.
9. Inspect and repeat if needed.
What is a neat thing about this pad is that even if you don't know how to use a rotary you can use it to remove some pretty serious defects via DA random orbital.
Depedning on the hardness of the clear, you "might" be able to go right to M205 with a gray finishing pad via the KBM. Sometimes a middle step with M205/orange pad via KBM is required.
Do not be fooled into thinking that this pad cannot cause damage, because it certainly is capable of removing a lot of paint in a hurry!!! This pad can damage paint. Do not think of it as some foo-foo lightweight pad. Be very careful when buffing plastic panels, bumpers, side view mirrors, and other parts that may have been painted using flex agents.
Surbuf pads are designed specifically for use on random orbit sanders/polishers and probably would inflict some major damage if used with a rotary. They are not like traditional wool pads in any way. Probably as close as you can get to being an all out furry sanding disk. Use the Surbuf pad as you would any other foam pads, and the result is very similar to that of a WOOL pad on a ROTARY! The Surbuf pad is extremely easy to clean and doesn't smell like dead sheep.
The Surbuf pad does a great job and makes quick work of correcting severe and stubborn swirls and scratches.
From now on if it's more than the orange pad and M105 can do I'm reaching for the Surbuf pad.
IMHO this method will level paint as good as a rotary.
