I used to spritz rotary pads with Meguiar's M34 as per the instructions that came with their pads.

I never do that with a random orbital.

I have however sprayed with my ONR spray to reactivate the abrasives in M100 while cutting. I just wanted to see how long I could keep things going without adding new product. Not my preferred way to do things, but I like to experiment when I have time..
