Simple PC Question (Pressure Applied)

Alright, I have been working with the PC for a little while, probably under 6 solid hours in total. All I have right now is a simple question about the pressure applied.



Should it be just before you can see it stop spinning, or just after you can see it stop spinning?



I realized that I have been using a lot of product, more than most from what I read, and I think I am using too much pressure, absorbing too much.



I believe I need to start using less pressure, and that pressing down enough to let it spin still, is where I should be, correct?



:o
 
In my experience, and from reading many posts on many forums, it is perfectly OK to use as much as 20 lbs. of pressure on the PC head, depending on the product. I think that you cause less marring when putting some pressure on the head, and get the work done faster.



IM NOT, in any way saying that you should be leaning on the machine, but the more aggressive polishes sometimes need some oomph behing them on tougher areas.



After a lot of trial and error, I think that the more aggressive the product, the more pressure it needs to do its work and vice versa.
 
Defects were being removed, and products were being broken down. It was working, but I had a feeling it should be working better.



It's not that it wasn't doing anything, it was just that I believed it could be more efficiant.
 
Notice how the movement changes when you apply pressure? It's like you solve one problem (not getting the job done with the weight of the machine alone) but cause another (the machine doesn't move the way it "ought to"). If you're working hard paint, the weight of the machine alone, or even with just a little pressue, won't accomplish much of anything. To really do correction on hard paint, you have to be able to apply pressure (hey, it's not a rotary ;) ).



Try using a 4" pad (with suitable backing plate) for the aggressive work. You'll be able to apply pressure without messing up the operation of the machine. I don't try to do significant correction with a PC and larger pads, it's just too inefficient. If I can't do the job with, say, #80 and a 6.5" pad, I use a different approach.
