I've really been wanting to try something like this. I've read up on your damp sanding article and such. However, I'm still afraid to jump into it because of my experience with wet sanding - when I wet sand, which I'm pretty good at, I turn off the radio so I can hear the sanding and listen for a piece of dirt or something that might cause deeper scratches. Sometimes I can feel it under the paper, but typically I can hear a high pitch squeak when something gets under there. So I'm afraid that if I were to use a power tool, although 10x easier which is what is attractive to me about the idea, I'm afraid I could be doing some damage that I don't know about...and instead of straight line scratches, get squiggly scratches, which would be even worse. I say this more as a question, than a statement - I really want to be convinced to go this route because it would make life much easier! :)

Great tip about working in silence to hear the dreaded high pitch screeching sound of an abrasive particle trapped between your paper and your paint.

As for trading the issue of tracers for pigtails, for the most part you're always going to get these defects when you wetsand, it's inevitable if you tackle enough real estate.

The benefit to machine sanding is it's,


Faster
Requires less labor
Removes a more even amount of paint over the surface being sanded assuming you use good technique
Leaves a more uniform sanding mark pattern



I choose machine sanding over hand sanding every time, the only time I will hand sand is when I must hand sand and there's always instances where you need to be able to do both.

One thing for sure, the Griot's Garage 3" Mini Polisher is my favorite sanding tool for small or intricate areas, for edging or for thin panels. Since introducing it in my classes it is always the most used and most popular tool among the students.

It's incredibly easy to control so that makes it easy to sand next to an edge and not sand on the edge, or sand next to a tape line and not sand on the tape line.


Machine sanding is so much faster than hand sanding that it's really worth it as far as your time goes.

If you finish out with #3000, #4000 or now #5000, if you do have a pigtail then it will be shallow and easily compound out.


Good question...
