I've beeen using it dry and I keep getting like, scuffs, that seem much coarser than the grit on the paper. I think it's from the paper getting loaded up. Seems more pronounced with more pressure. Should I be doing this wet?

I use wd40 seems to work better than water, plus it stops rusting....
Water works better than dry, WD40 is also a good alternative.

Wet and dry sandpaper is designed to be used wet so as to wash away the build-up that is being sanded. That being said, W&D sandpaper can also be used dry, if the build-up and cost is of no concern.
If using W&D to hone a SR, build-up would be a concern to me so I would use it wet with running water to wash away the build-up. When using W&D to lap whetstones, I also use it wet do as to wash away the build-up.

Thank you gent's. WD40 is the bees knees! I can't believe the difference it makes.
I use wet. I’ll have to truly WD40 sometime. I’ve seen some beautiful mirror finishes done with it.
Wet and dry paper was designed to be used wet or dry - hence the name. Adding lube; water, oil, etc, helps minimize the depth of the scratches on the material being sanded, and the wear on the paper. Using it dry will allow faster cutting. This week I had to take a ton of oxidation off an old weightlifting bar - 220 w/d used dry helped me cut through the grime fairly quickly. Using it wet afterwards gave me a finer finish. Sorta like having multiple grits in one paper. I do the same with razors... 220x is the coarsest w/d I keep on hand, I don't like 150x. So I'll use 220x dry first and wet second. If I really want to bring up the shine I'll use an oil type lube after sanding with water but I'm usually not that motivated.
