When it comes to using any kind of tool, how well it works depends a lot on "The Nut On The Handle!" You may be familiar with Big Daddy Ed Roth of custom hot rod fame? He got his start painting cars with his Mom's Kirby vacuum set up!. If you are ever in the St. Louis area, stop in Mark Twain Hobby in St.Charles and check out the Fock-Wolfe D-9 hanging in the shop. it was painted with the cheapest Badger single action spray gun available at the time, which cost 5 bucks then, I think. So if it works, and you like it, keep calm and carry on!
