I’ve never heard of or seen a “wet” system for mini-dv…only “dry” systems. I think it’s because it has something to do with the way it removes the tape particles from the heads.
I don’t see why it would be like sandpaper. That’s what I’ve been using in my Canon ZR45 and Canon GL2 for years, no problems. Just be sure to clean the tape heads everytime you change tape brands.
