What would be a better purchase....4" pads for a PC, or a rotary polisher?.....dollar for dollar, would a polisher be that much better?...i keep hearing about the effectiveness of the 4" pads on a PC
A rotary is a huge step up, however I paid 220 for mine. The 4" pad kit for a PC shouldn't run over 50. If you have scratches, etc that you just can't remove by PC, go for the 4" pads. If you are looking to do production work/work faster, go rotary.
I'd say the same thing. And I kinda like the idea of working with the PC to the point of having fully exploited its abilities. THEN get the rotary.
But I gotta say that I could just as easily argue the other way too, the rotary is a really handy thing to have...but all-in-all the lower cost (and yeah, the admitedly lower performance ) of the PC's 4" setup makes it sorta a no-brainer to me.
Much as I tend to recommend expensive stuff, when somebody expresses a concern over cost I'd rather *not* recommend a big expenditure unless it's really needed. How badly do you really *need* the rotary? If you're not a pro it's all a matter of "how much better do you want to get hard paint in less time" and how often. FWIW, I can keep the MPV the way I want it without using the rotary but I can't do that with the Audis.
