Tarps work really good for recycling the media, just keep reusing it with new added in as needed. When it quits working or is creating to much dust, let it go out in the yard, sand is good for lawn.

Something else, watch the weather forecast, you want dry air while blasting, and at this time of year, that may be hard to come by! Make sure your air line has a good dryer on it, the moisture in the line will rust clean metal.

What type of paint are you going to use? That will determine how good of a job you have to do. Por products don't need 100% clean metal to work, but if you are going for a show quality frame with gloss paint, better plan for a few long days of blasting.
