Has anyone experience of using the 'pot type' total loss sand blasters that turn up on eBay regularly at about £80 ? Basically a 10 gallon pressure pot with suitable hoses and nozzles ? I need to strip back several square meters of grotty paint on sheet metal, and a bit but no too much thankfully that is rusted.
Are they resonably effective? Can you infact collect and recycle the media with strategically placed poly sheeting? What media (I assume dry sand is out due to silicosis) to use ? They claim 6-25 cfm air use - or do you really need a road compressor?
