Vroom - I do use Tig with helium/argon or sometimes plain argon if Im too lazy to swap tanks. I use 1/16" 1100 filler but less than for a regular weld.
With Tig , both side have to be welded (no filler on the back tho) so you get 2x the distortion of gas welding. I gas welded some small parts but never the large ones. Def a skill I need to get more proficient at.
If you decide to gas weld aluminum, check out Kent White's store and videos, buy his products, and do what he recommends.

An English wheel is really necessary to get nice panels, otherwise hand tools are all that is needed to get going. I do use the torch to anneal often, but I think it could be done with MAP. I think a bead roller would be machine #2.
Here is a pic from a. few weeks ago. I have since mounted the taillights in recesses and done a lot of inner structure work. Ill post a newer pic this weekend
