I think your a little shy on the air system, and perhaps the paint supplies....people forget things like connectors, wire and what not for air systems.....of course if you are doing the install you will save, but don't forget welding gas, wire, sanding and grinding discs sawzall blades...these things add up.
Same with paint, tonnes of sandpaper, sanding blocks, primer, filler, sheetmetal, base clear, reducers, hardeners, adhesion promoters, and specialty colours really add up fast. Again if you do it yourself you will save, but if you've never done it expect to do certain things twice.
