That could be your problem. In just a couple of panels you can build up enough heat to damage the pad. I typically use 3 sets of 2 pads and alternate between the two to allowing them to cool. Then when one set gets full of product that can't be removed with cleaning on the fly switch to a fresh set.
Here's an article by Mike Phillips:

From the article:
"Switching to a fresh clean, dry pad OFTEN means less wear-n-tear on pads in general and you'll get more use or extended life out of each pad overall. Pushing a pad to the point that it's completely saturated with product wears out the foam, the Velcro and the adhesive faster than stopping the use of the pad after a panel or two.
Buffing with wet pads increases the heat retention inside the pad and to the backing plate and heat is never a good thing in any buffing process."
Correction step = 6 pads
1 for the hood
1 for the roof and trunk lid
2 for driver's side
2 for passenger side
Polishing step = 4 pads (You could probably get away with 3 if you use 1 for hood, roof and trunk lid)
1 for the hood
1 for the roof and trunk lid
1 for driver's side
1 for passenger side
