I dont think I understand how using any product, with a PC can cause pits? The pad is in constant motion. Pits are created in a single spot, or single points. With a pad in constant, random motion, the only way I can envision pits being created would be if the polish contained individual abrasive granules that could, somehow, get lodged in the paint, and then the motion and pressure of the pad would, instead of moving the abrasive around and diminishing it, instead just grind it into the spot where its lodged, making it go deeper. IT sounds awfully weird, and Ive never experienced it.
I DO have pits on my hood, but that comes from a couple of sources I believe: First, the hood, being on the leading edge of the car, is the surface that is most exposed to road rash, ie, gravel, sand, and small natural abrasives kicked up on the road as we drive. In an attempt to deal with this damage, my hood has less clearcoat on it than the other surfaces, simply because its been polished more frequently since its exposed to more damage. I think the road rash, combined with the thinner clearcoat is whats giving it its pitted appearance.. But in my case, I had the pits before I ever used the 2.5. The pits, btw, in my case are tiny depressions in the clear that are about the thickness of a heavy strand of human hair. Ive been reluctant to try and polish them out because the clear on my hood is a mil thinner than what the roof ant trunk surfaces measure.. I measured the roof at 7 mils but the hood at 5.5 to 6 mils. So iM very reluctant to use anything stronger than 2.5 on a polish pad. And even that is a little too strong for my liking going forward. Probably use Finesse-IT on a cutting or polish pad in the future on the hood. Then, I may just have the hood repainted sometime in the future.
