So I thought a friend of mine was pulling my leg, but he insists he is serious on this. My friend told me along time ago, before he had a 120 gallon compressor, he used a garden pump sprayer to paint his fence, and then later to varnish some furniture. He said he had to thin the mix down alot and play with it to get the nozzle set, but it worked very well as long as you kept the pressure from dropping too much (pump it up often). I don't really intend to do this since I'm rolling everything, but it did spark my interest. Anyone ever heard of this technique? It sounded nuts to me, but then I figured maybe it works kinda like a wagner or something.
