As I have mentioned in the past the Festool Granat sand paper is pretty amazing.
The link below shows me sanding a corner joint with a moderate amount of glue squeeze out. The piece of paper in the video was used on the previous TV project to remove a layer of stain and varnish from the cabinet top. It also did a lot of joint sanding with glue squeeze out also.
In this project this same piece of 120 grit paper has so far sanded 32 glue joints with moderate glue squeeze out.
Note I am using the Rotex sander in the aggressive mode. In normal ROS mode it takes approximately 3 times longer to remove the glue or about
10~15 seconds per joint. Still not a big deal time wise and as you will see the paper has not yet begun to load up with dried stain, dried varnish, or dried glue.
