I wanted to share with you guys the resource where I learned the most about painting.
http://www.autobodystore.com/cgi-bin/config.pl?index
The site sells painting supplies, equipment, tools, etc but it also has a web board where some fantastic bodymen, collision techs, and painters discuss techniques, products, as well as answer questions from novices. There are some real heavy hitters amongst autobody professionals at this site, and the archives are as valuable a resource as I have ever seen.
