If your learning metal work or know all there is to know.
Here are two sites to check out.
http://www.allmetalshaping.com
This first one was started by my good fried Johnny Arial.
The second Metalmeet.com was started by a man named Wray Schlinn. (might have spelled the last name wrong for Wray.
They are both really GOOD sources for learning to do it CORRECTLY.
lots of wheel, metal finishing and hand work you all and myself could learn.
I know it is easy to just throw bondo (mud ) on sheetmetal, but hey if your interested in doing correctly check these two sites out.
