Troy asked me to come add a bit of info here. First I'll answer about the cool pad and then add to what Charles said and respond to part of it.
Paul, the hybrid pad you mentioned is the "coolpad" it's an MF/wool hybrid and cuts faster than other MF pads out there. If you want to get super fast correction with a D/A toss it on and prepare to be impressed! One finishing step with foam afterwards and your done. Try it out and please give me a ring or email and let me know what you think.
As far as heat buildup that is something that with certain pads and tools we always check the surface often. With orange peel pads specifically you would want to work a large area to allow it to stay cooler, of course check the surface often especially if doing a small area.
You don't buy one of these and just start hammering away without testing it and becoming comfortable with it first. Just like when learning how to sand you don't just go straight to a Ferrari to learn on. Work a test panel just like you did learning how to do anything the first time.
I will add to what Charles said by saying with the orange peel reduction pads you will find the gloss is not removed like it is with sandpaper therefore you MUST be cognizant of the fact you are removing lots of paint even though it's not as obvious as it is with sandpaper.
They come in very handy for aggressive removal of many things but don't replace sandpaper completely. They reduce orange peel very well but it's something I would be careful with on factory clear. Checking with a paint gauge, checking heat, etc.
Ive used them personally to get a feel and test them but I haven't used them at length the way some guys have. There's an article over on DW that was well written about them. Also, if you Pm Bryan W (Bryans best wax) over on Live2Detail he can give you some more info. He's been using them a lot with great results. John from Perfections used them to take out some serious oxidation from a nasty repaint he was working on. He felt (and I would agree from my testing) that it's easy to clog them up in those situations. It's another great tool IMO, better than sanding some times and not as good for others. You save yourself a step by not having to compound after using them like you do after sanding however you don't level only the tips of the paint as fast as you do with sanding.
Again, learn to use first and don't go applying pressure just because the paint looks super glossy and you don't think your cutting, you are!
