Wet sanding is done on cars all the time. A liquid will make the sandpaper last longer,clog less. and glide smoother. Also less scratches.
I seal the ends of wood pen blanks with a dab of thin CA before sanding. If i need to touch up before assembly it is very easy to do.
I even go as far as using lemon oil when I wet sand my woodworking projects that use exotic woods. because of the tight grain and the oils it just a natural to do. They polish to a mirror shine.
I got a laugh out of it, I googled lemon oil to learn a little about it and there was a post citing 10 reasons to use lemon oil. I'm saying to myself I'll post this for a laugh and get him John with it, but lo and behold Dr. Axe's #6 of the 10 best uses for lemon oil is 6. wood and silver polish. Who would argue with Dr. Axe? Not me.
Would the lemon oil eventually clog the sanding pad or do you frequently use soap and water to clean the pad?
How much life do you get from these pads?
