I needed to do a relatively small spray job. It was too small to be worth dragging out the air hoses and starting up the 3-phase compressor. I went to the local hardware with the idea of buying 3 or 4 spray cans. Nice and easy, throw out the empty cans and the clean up is finished.
When I got there I spotted this Ozito Spray Gun for $39.95. Buying a can of paint and this spray gun wasn't that much more expensive than buying the aerosol paint cans. While I realised that cleaning would be as much an issue as with a normal compressed air spray gun I decided this might be useful for small jobs and in the long run would be cheaper than buying aerosol cans.
