4in. pads or 6in?Need help

Which PC? New XP or older version? You could split it in the middle and use the 5.5 inch pads. A lot of people use the 5.5 and switch to the 4 inch for tight areas.
 
It's for the older PC. I also have a makita 9227 for the larger surfaces. The backing plate I have now can adopt the 6inch pads.

Ok so 4 inchers it is. Any particular reason they work better?

less weight. Too much weight on a PC = less/little or even no pad rotation = less/little even no correction.



I would never use anything bigger than 5.5" with a PC. 4" for more/quicker correcion. Be aware that with a 4" pad some heavy compound, some weight added onto the machine and just the right paint situation (esp on plastic) you can burn the clear.

I also only use my 5.5"pads. Haven't needed 4" pads myself, I should really get some "just in case".:think2
 
I use the 5.5's on a regular basis, and the 4" only on panel repairs or scratches. Very rarely do I use the 4" for an entire job. Matter of fact, I think Ive used them twice for a complete job.

+1

they work better because with the DA polisher the ''power'' is on the center of the pad, and with smaller pad it is spin faster than bigger....I mostly use 5,5'' pads and there is a huge difference comparing with the 6'' pads....4'' are much more better than 5,5'' pads though :2thumbs:
 
Now im not sure if I can run 5.5 inch pads with the curent backing plate that I have on now. My friend that sold it to me told me to get 6" pads to go with it.
 
If you're getting into detailing for your own cars or as a business, even a weekend hobby, then you really want to get a combination of both 4" pads and then larger size pads also.



4" pads are good for serious correction work and also for thin panels when you don't want to be buffing onto of an edge or body line.



5.5 and 6" pads can also do correction work and also cover more surface area faster. It's just an investment you need to make in order to be able to tackle the entire project.



The older Porter Cables don't have the power tools like the Meguiar's G110 and the new Porter Cable 7424XP offer and the increase in power these two styles of polisher offer is enough to make any correction work go faster.

Its just a PC7424, as mentioned earlier I also have a Makita 9227 Rotary to go along with the PC. The 7424 currently has a backing plate on it thats good for 6in. pads. I dont know the diameter of the current backing plate but I MAY be able to stick on some 5.5 in pads.
 
Let me tell you, I switched to 4" with my G110, just so Accumulator would stop his constant nagging about 4" pads and I havent looked back. Its faster for me and gives better results.

IMO it's less friction. This makes it easier for the rotation to keep happening under some pressure.

^^^^^ ....I believe it has more to do with this than anything else.



The 7424 has a forced orbit but not a forced rotation. The added friction larger pads create will begin the bog the machine down as more pressure is applied. ....to the point where it will stop "spinning" and continue to simply "jiggle". Having used 6.5" and 5.5" pads with my PC (v.1), the difference in performance was immediately noticeable with the smaller pads. IMO, anything larger than 5.5" is counter productive.



I will be doing some correction on a car with harder clear for a family member in the next few weeks so I finally placed an order for several 4" pads. Depending on how this goes, I may join the ranks of folks like Accumulator & Craig touting their effectiveness.

Heh heh, I love it :D Glad I'm getting throught to somebody!

I just might have to pick up one of these newfangled machines and see about the diffs for myself :think: Sheesh...another, *eighth*, polisher?!?
 
I have only used the Edge system 4 inch pads and I am a huge fan of them, I believe that I get better correction each pass with the 4 inch pads so is it really slower if I go over each panel a fewer number of passes? I don't think so. I will continue to use the 4 inchers until I grow the stones to get a rotary.
