I'm looking to spray a vehicle or two on the cheap. I'm looking for products that are the cheapest available, but of reasonable quality. I have a suitable compressor, air line and a gun. Oh and a face mask. just need the rest to get up and running: Water separator Gun pressure gauge Paint Filters Thinners Mixing cups Wax and grease remover (do I need this or can I use something I already have?) Gun wash Anything else you can think to add to the list. Is it ok to get everything off ebay for the lowest price? Are there things I should avoid? Are there things I should not skimp on? Thanks for the help!
