I weighed the goop-vs-grit argument too, and went with bead-blasting. $600 too. I figured vacuuming and blowing out the beads would be far preferable to smearing and scraping, and would clean the surface better. Beading also removes any metal that isn't of a certain thickness, even when hidden by Bondo. I also beaded every other metal part that needed or could use painting (I have a bead cabinet available). I have also seen mention that beading effectively shot-peens the surface of the metal, reducing its surface porosity and making the "skin" harder.

Along with a vacuum I would strongly recommend compressed air. There are a lot of tight spots that a vacuum can't reach but 80psi air will.
