Hey guys. I wanted to share a new sanding tool I found. They are adhesive backed sanding dots with a mandrel for a rotary tool. They are from Dspiae. You get 96 dots per grit. I save a bunch of money by purchasing an off brand battery powered rotary pen that charges with a USB-C cord. The mandrel is held in with a set screw. I used it for the first time today to remove the injector pin marks in the inside of the Case tractor fenders.
I have some ideas on how to fix that. They're not very good ideas, but at least they're ideas!
