The packing oil is not the typical packing grease. It's a light machine oil, like mineral oil. I thought it unnecessary to clean it thoroughly with acetone, only to put another oil back on. Boeshield plays nicely with mineral oil. I just wiped off the excess.
A scraper still works well if the glue has partially dried.
The chisel plane can also be used to pare dowels and dovetails flush to the main surface.
I have a Bullnose plane that I use to do the same thing, mine is not as wide as the one you are using, but it sure gets the job done, I agree, way better than a chisel or a scraper!
Nice tool but a kinda pricey glue scraper. I use a paint scraper for glue and a plane for wood. Seriously, a paint scraper makes short work of glue squeeze out. But I truly agree with Alan's last comment about satisfaction and quality tools.
I learned something from your video. That, alone, makes it a good video. You did very well with camera angles, lighting, etc. I was impressed how smoothly you moved the camera (no jerks or bounce) while walking. You make the plane sound very interesting.
