Default Re: Porter Cable Kit Question

Wow that was an incredible response Mike. I am deeply appreciative of the time you put into it and I apologize for the long-winded questions. Hope this also helps others out there too as these "kits" imply they contain all you need. Autogeeks tech service strongly recommended the PC kit for the situation I described above oxidation-wise (and yes its the PC kit that you attached), but I assume it goes with common sense to realize that there is no "one size fits all" approach out there, especially with boats and gel coats.

Specifically a few follow-on questions with assumptions:

Isn't the Porter Cable a DA Polisher? I assume you were using different DA Polisher like the Flex since the PC isn't strong enough.

Rotary buffer (I assume is synonymous with rotary polisher when I am rreading various forums) - is this any old 7" grinder found at Harbor Freight or Home Depot equipped with a buffing backing pad?

Should I just return my PC and replace with a Flex kit (3401 vs 3403)? I don't want to break the bank here and don't think I can afford both.

Are Flex units free spinning and not good with wool pads?

So assuming again that both the PC and Flex are DA Polishers, will the Flex Polisher not be a good enough choice for removing heavy oxidation and should I just get a cheap rotary buffer with 1 wool pad to do that work?

Kind of wondering if I need to trade out the PC for a Flex and then add a cheap rotary to the mix (or just add a rotary to my PC kit I just bought).

So I guess its normal to do nothing to the wax application foam pad and just store it cleanly between uses?

Looks like at a minimum addition of a few cleaning tools and a bunch of pads is in order.
