Foam pad size

[Jeep63]

Hi to all,

I'm new to this forum which I see has alot of usefull information.My question is I Have a PC-7424 D/A polisher and a Hitachi rotary polisher.Is it best to stay with the 6 1/2 inch foam pads with both or use a larger pad with the rotary?I know the smaller pads make the machines work less harder.Thanks Joe:buffing:

I wouldn't use anything larger than 5.5" pads with the PC. Some 4" pads are also good for smaller areas (bumpers, fins, etc).

Make sure that you have a 5" backing plate for 5.5" pads and 3.5" bc for 4" pads.

I started with 6.5" pads but have since switched to all 5.5", fwiw.

Tad pretty much nails this one. Even on my Makita rotary I stay with the 6.5" pads.

Same here. 5.5" is so much better on my rotary

Hmm, When I got my G110v2, it was recommended that I get the soft buff 7's. I was told the larger pad reduces chatter?

Thats what I have been using and like them. But, my experience is limited. So would my results be better if I go smaller? How does this improve the performance?

So why do so many car kits offered here include only the 6.5" CCS pads? I was told "they are safer...less likely to cause any damage". So is this a case of the seller protecting their own butts? Why not give the people what they want? I don't get it. Why don't all the kits allow you a choice...and not be forced to buy the 5.5" pads seperately....Ohhh....sorry, now I get it...$$$$$$...!!!!...duhhhh.

Well I like my 7" ... Maybe if you're a pro 5.5" works just fine.

Serious though... what are the benefits to a larger pad? There needs to be something or they wouldn't spend the money on developing them. But, I do think I will try some smaller ones to compare.

More surface area of the larger pad providing the polisher can spin the pad.
