General Finishes has been trying to step up their game a bit in the area of education. Lately they have started doing a few web-casts and medium length videos where they demonstrate some aspect of their product line. If you find their YT channel, you can look up the other web-cast style videos.
Here's one that deals with dry spray from HVLP (I think he is using only turbine units in the demo but you get the idea). Good general demo of the PPS system too.
GF has good products and of course that's what he is using in the demos but the information scales. Not a huge fan of the faux finish stuff but on the whole, some good info if you remember you are also watching a commercial.
