Baseboards can be a pain…if you have a big job to do, this Racatac rig might be just the ticket. Better than knee pads, the seat helps take the load off the knees. Also good for wainscotting, etc.
I think I could get used to this gadget:

I borrowed it from the tile setter…the model with the tool/paint tray in the middle would be good for me. They start at $189.
