I got the Paintshaver. Here’s what a couple passes per siding board does. I’m testing it on the garage, learning to not take off too much wood. The bare wood is rough and needs to be sanded and/or skim coated.
Here’s the tool, connected to my HEPA vacuum. Almost all of the paint chips are captured by the vacuum.
These are expensive ($1000+) but I got mine for $227 on eBay :-)
My neighbors are anxious about lead paint and don’t understand that I’m sanding bare wood and spackle, so I have to wet sand by hand :-(
