I have a cheese grater and a pretty good da sander. Will the d a do a decent job of quick sanding the initial coat of bondo? I've been watching lots of body shop videos on youtube, and most of those guys use what they call a bondo hog. Since this is probably my last project, I don't really want to sink hundreds of dollars into a sander. I'd like to use some sort of powered tool to rough cut the bondo, and then finish subsequent coats by hand. Any suggestions.
