The drawback with the wet DA IMO , is you loose the ability to feel if you pick up grit. If you do it does a number and then you got pig tails to deal with. You can actually hear it scratch , but then the damage is done. More if an issue if your outside or in a shop with 3 other guys working etc. We use it for production work, gives a perfect OE look. If me our whoever goofed up, usually we just nib the few spots of dirt and mini buff then out the door it goes. If im doing something nice I paint stick and durablock with 800 or 1000 then go to different sponges, then bare hand with the Mirka Abralon pads. It's easy to spend a 40hr week prepping clear for paint. There are multiple ways to get to same result and everyone has their methods, and you'll develop your own as well. But you've got options Ken, what you've done so far looks great, I know guys that have done this stuff their whole life and your work appears to be much better.
