For a newb, what type of paint setup would a guy need to do a little of his own paint jobs? I scanned over a few paint guns....which is better, siphon or gravity type? Do you need a diferent gun for paint and primer or can you just change nozzles? and last but not least, what' the minimum type compressor you can use? I just want the basic setup to play with and practice around with, maybe paint a tank or two......but my ultimate goal is to do a paint job on a '73 VW Beetle i hope to someday restore. Any points in the right direction would be appreciated!
