Welder advice - where to start

TIG has it own criteria / aluminum/alloy's / stainless I wasn't suggesting quarter panels but like my fan shroud I had made up, my buddy bought it AFTER I had it made :BangHead:
TIG is artwork My same buddy used his TIG machine to weld on the frame rails I got from Dartnut….. you almost cant even detect that they are welded. Such a beautiful job. Watching him perfect the fitment before welding was like watching Michelangelo painting.
