I'll try my best here to explain the process.
Kevin created this method as well. Maybe he will post his full writeup on the process here.
I used it yesterday on a 04 Mystic Blue BMW 330i. Sorry there are no process pics, but I had to get this one done and delivered back to the client.
1. M105 original formula (I have not tried it with the new M105 yet.)
2. 7" Surbuf R series pads. They come in a pack of 2 for approx $20 shipped.
3. Porter Cable 7424 or equivalent
4. 6" backing plate works great for the 7" pads.
5. Spray Bottle of water.
6. MF towel ready to go.
7. Softer brush to clean the pad.
8. Compressed air source.
When the pad is new give a quick brushing and shot with compressed air to release some of the loose fingers.
Do not prime the pad.
This is not the cleanest way of polishing, you may end up with a good amount of M105 in the seams if you don't tape them. I don't tape seams.
1. Apply 3-4 larger then pea sized dots of M105 to the pad.
2. Spread out the polish on the surface (start with a 18"x18" area) without turning on the PC.
3. Spray some water on the polish covered surface.
4. Again spread the polish around w/ the PC off. Adding water to the M105 will give the M105 a milky consistency.
5. Turn PC onto speed 6 and apply medium pressure while working the polish.
6. You will notice the M105 turning more white as it starts to dry out, apply more water with your spray bottle and continue working the M105.
7. If you need to work the area longer, spray more water on the surface.
8. Leave the polish a little wet and wipe it off right away.
9. Inspect the area and repolish if required.
10. Finish with M205 and a gray LC pad or whatever you use to final polish with.
Cleaning the pad:
1. After each panel give the pad a good brushing and blow it w/ compressed air.
2. The pad will become caked up with M105 after a while and the fingers will be compressed. Spray a small amount of APC on the pad and rinse it out in warm water till it rinses clean. Spin dry on a rotary and give the surface a good burst of compressed air.
3. I usually use the 2nd pad while the pad I just cleaned dries.
What you need to figure out is the correct combination of:
1. Amount of M105.
2. Amount of pressure-With the 7" pad you can apply a good amount of pressure to remove deeper defects.
3. Amount of water to spray-1 pump will usually work.
It took me about 1/3 of the car before I could get it figured out. I am sure I will make adjustments to my technique as I go.
Some have posted that they can remove 1500 sanding marks with this process.
Defects on the car:
Right side of the hood before shot:
Left side of the hood after M105/205.
All done:
