Shown are an etching primer and high-build primer product from PCL. Also shown is Metalprep, a metal preparation product from Henkel Technologies which can be found at most automotive paint supply outlets. Two very basic HVLP gravity-feed spray guns from Harbor Freight are also shown. These are great for the beginners or low-end work as they are very economical. Don't show them to an automotive body purist because they will more than likely berate you for buying cheap equipment. I received the evil eye from the guy at the paint shop when I brought mine in looking for a regulator. The bottom line is that they serve their purpose and will save you about $120.
