Look in your phone directory under Equipment Rental or Rental Equipment. Rental runs around 30 dollars per day. Usually they carry top brands only and are industrial heavy duty machines.
the only difference with a sandblaster is the tip. but you need a decent air compressor. walmart sells the gun, adjustable nozzle and a variety of sand. its 30 dollars to own it.minus a compressor. youll need silicon sand to frost windows,and sand to stip your deck,stucco or metals
Look into media blasters. Just using sand will blow holes in metal, warp it, and make it tougher to finish. Other media, like walnut shells and the like, are a lot better, and not harmful to glass and chrome. Check first, buddy. Peace.
