I have to admit, this one was thrust upon me. I recently got hauled at a yard that required the use of dustless sanders. I got an orbital sander that uses the sandpaper disks with the holes in them and connected the sander to my shop vac using a length of cheap corrugated sump
pump hose. What a difference! Not only did I come out from under the boat without being covered in
paint dust, the sander worked more effectively since it wasn't re-grinding the same dust over and over.
