I have used the Porter Cable 7424 for years, but recently noticed that a 5.5 inch pad was recommended. I have always used the 6.5 inch pad and noticed in many of the videos that Autogeek has provided for us to view, that Mike Phillips even uses the 6.5 inch pad on the Porter Cable. This has confused me a little. Why does Porter Cable recommend the 5.5 inch pad instead of the 6.5 inch pad? Obviously, the larger pad provides more coverage, but I would like to hear from those of you who have more experience than I in this field. Your comments will be appreciated.
 
I have always used 6.5 with every pad except the Red Ultrasoft Pad 5.5 as it is super soft and meant for final applications of sealant/wax. I find easier to use due to the fact that it can fit into smaller areas and curve lines.
 
The PC can easily bog down with 6.5" pads on curved panels. Not always, but the effect is lessened with 5.5" pads. The PC isn't the most powerful machine, and it just seems to spin a 5.5" pad much easier.

You got to remember, Mile Phillips has been polishing paint for umpteen zillion years so he probably could use any pad to get excellent results. For the average noob or weekend dude who picks up a buffer a few times a year, 5.5" are just more use friendly. Also, if you want to use a PC at lower speeds 6.5" pads often won't spin well, or at all.

However, with a Griot's, I use a 6.5" pads all the time. I think it could spin an 8" pad no problem well. One of the benefits of a Griot's over a PC.
 
Actually it does recommend a pad. Located on the eccentric plate is the following statement: "Use 5 inch pad only."

They mean a sanding pad. Until a few months ago they were no 5" foam pads and the PC has been out for years.
