I’m doing some automotive bodywork/painting on my car, and the sandpaper/wooden block is really startign to get annoying. I know bodymen use ‘dual action’ pnuematic orbital sanders, but would a 5" electric orbital sander do the trick? Shops have compressors and other expensive gadgets, so maybe using Air > electricity is more convenient and reliable. Any advice? Most DA Air sanders are 6-8inch, and I have only seen electric sanders up to 5".
Will the smaller size make waves and crap in my metal, or will it work for the one project I plan on using it for?
What the hell does ‘dual action’ mean anyway?
