Amount of pressure

[04 Hemi]

How do you know when you have applied enough pressure on the PC. I just recently got the PC and have been experimenting with the pressure, but i have noticed that the more pressure you apply the slower the speed it spins at.
So here is my question is it better to use more pressure eventhough it has a slower speed. or less pressure but a higher speed, when it comes to removing more defects.
I have been doing two passes with addequate pressure and then one or two with almost no pressure at all, just in case it makes a difference, just wanted to see what eveyone had to say about it.
Still very happy with the purchase of the PC.

glad to hear your happy with the PC
the amount of presure you apply depends on the product that you are using.
heres a good tutorial

There's a balance between too much pressure and too little pressure. I've seen the pad on the dual action polisher stop rotating with light pressure and with heavy pressure so the tool's mechanism isn't as predictable as you would think it should be.

Also two factors that come into play as far as the rotating action goes,

1) Pad saturation - When you first start out with a dry/new pad it will rotate less. As your pad becomes broke-in, i.e. more wet with product it will tend to rotate more.

2) Product choice - Some products are more slippery than others. For example M80 Speed Glaze is more slippery than M83 Dual Action Cleaner Polish and your pad will tend to rotate more with M80 than with M83

The important thing to remember when removing defects is to only tackle small areas at a time. Most people I have met either in person or over the Internet that are not getting the results they're hoping for are trying to tackle too large an area at one time, for example, half of a hood, or even a quarter of a hood. If you have swirls and scratches in the paint your goal is to remove them, then because the oscillating action of the dual action polisher is gentle, even at the 5.0 setting, (place the polisher while it's on against your hand and you'll not it doesn't hurt or remove your skin), then in order to remove swirls and scratches you have to focus your energy on smaller areas.

Work a small area then add some more product and move on to a new area. Be sure to always overlap into the previously worked area.

This car here built by Troy Trepanier is a beautiful car, but when I inspected it, you could see light swirls instilled by a rotary buffer. I carved out small sections at a time using M80 Speed Glaze with the G100 and was able to remove the swirls.

Thanks for the Info, so i should just keep moderate pressure regardless of the head's speed. Since it will vary depending on product and situation.

For removing defects, yes. I do.
