I recommend the compressor and HVLP route, and in this instance endorse cheeping with a harbor freight gun. Harbor freight paint guns will work well for what you need and when they inevitably wear out due to the nature of glaze (abrasive particulate) running through them you won't feel it in your wallet as bad. Do make sure you get a big enough compressor, lack of air volume and low psi will give you fits if you are spraying a lot. I have two HF paint guns one detail size and the other a standard size, both gravity feed, which I would recommend over a syphon style gun. You may have to play with thinning out a glaze or adjusting to a higher psi on your compressor to have good results. You should think about running your glaze through a screen or mesh too, even body shops run their paint through strainers and adjust viscosity with thinners to achieve desired results, not that you are painting a hot rod. No matter what you do if you adjust the glaze test and take notes, you will be glad you did, but above all else enjoy the journey.
