Re: Porter Cable 7424..?
It's almost impossible to cause any damage with this machine (just don't drop it on the hood of the car!) so I would recommend to teach someone the proper technique from the get go. Use speed 5 to work a polish, speed 3 to apply wax/sealant, and speed 5 to remove the wax/sealant. All with the appropriate pads, of course.Michael Stoops

I agree... The PC is a very safe machine that just about anyone can use provided you are using the proper pads and products.Brandon

Re: Porter Cable 7424..?
What I find with the PC for serious buffing is that it's not only slow, it takes a lot of effort and theirs heavy vibration. The #1 mistake I see from people going from rotary to PC is they move too fast, you have to move really slow with a PC and press really hard. I think Mike said 15# force. For me the PC works out well for putting waxes on and for buffing cars where you can't afford any splatter like our convertibles as it's really a pain to get polish splatter of rag tops, especially our Wrangler.

Good insight Buellwinkle, that's one of the things we teach in all our classes since we started them back in 2002
The History of our Saturday Detailing Classes
Meguiar's has always placed a strong emphasis on education ever since entering into this business in 1901. Meguiar's moved to their current headquarters here in Irvine, California in 1989 and since that time has always offered educational hands-on classes in our Training Facilities. With the advent of the Internet and the introduction of software to create what we call discussion forums, we began coordinating our classes held on Saturday through discussion forums as it was a way to easily reach car clubs represented by their online communities. Our first class coordinated through the MercedesShop.com Discussion Forum was held on a Saturday here at Meguiar's dates back to August 31st, 2002 We're happy to say that many of the friends we made through this class are still friends today and a few are even active members of our forum.
The time stamp on this thread is 07-11-2002, 10:46pm and the class was held on Saturday, August 31st 2002
SoCal Mercedesshop, Meguiars Detailing Day In August
The sign-up thread is 8 pages long with the pictures and comments after the class being posted to the same thread starting on page 6 It has 115 Replies and right at 6000 views since it's creation and the posting of this thread.
Here's the only two pictures we have from that event although were trying to locate a few more...
As for the pressure, it's not actually a point blank 15 pounds or any number of pounds, how hard you press down on the head of a dual action polisher is determined by what you're trying to do. If you applying a wax then you use light pressure, but if you're trying to remove below surface paint defects then you need to remove paint and when using a dual action polisher, because most clear coat paints are harder versus softer, you can't remove paint by using light pressure, so "yes" you do need to apply more pressure for the cleaning step. But you have to balance that against keeping the pad rotating because paint is remove best when the foam is moving over the surface not just jiggling on the surface.
Does the above make sense?
I'm confident we covered this in the class you attended back in November of 2004
