I recently purchased a PC random 6 speed orbital buffer and all the pads and conditioners and such. Today I washed the car, clayed the car, then began to buff. I began using a fine cut cleaner with corresponding pad to remove the fine swirls. However I was a little confused on which speed to begin with. I was also dissapointed becuase it didn't remove any of the hard water spots, however I beleive I will just have to get a more abrasive compound.

So basically I am asking what effect the speeds have on the cutting power? (Like: The higher the speed the higher the cutting power?) Or Visa Versa?

Thanks everyone, you have corrupted another young soul into a detailing maniac. Luckily for me my car is black so I can detail my little heart out!

 

In my experience, I've always used speed 5 or 6 whenever I've had to do any cutting. Polishing, I will use speed 5 and applying any glazes I use 3-4 or less.

Are you working slow?

 

When you say slow do you mean moving the buffer slowly?

If that is what you mean, not really, I am not letting the buffer stay in any spot for more than a fraction of a second. I'll move it horizontally, vertically, horizontally, vertically, etc. until it begins to almost powder, then I wipe and check my progress with a drop light. And if needed I repeat.

 

watch this to have an idea on how to use the PC

You'll need to experiment and do what is comfortable for you.....I have found that with speed 5-6 it is harder to keep the pads on, particulary when dealing with contours in the panels. Perhaps I need a new backing plate [&:]

I use speed 5-6 when using compound, speed 4-5 when polishing, and speed 3-4 for the glaze coat. Don't apply too much pressure, let the pad and chemical do the work. You should be holding onto the machine just for guidance, and move VERY slowly in the repeated vertical and horizontal motions as you mention.

You might need to start out with a true compound and the orange pad if you are having troubles with the swirls. Then move to the white pad with polish.

 

sowaxeman, You definitely need a new backing plate!

It takes a lot of effort to remove the bads from the backing plate. Do it before you have a catastrophe on your....paint!
