Stop in for a cup of coffee

Need some small tips for sheet metal.
I used to think MIG was better for sheet metal. Now I think its only better in some situations.
If i could learn to tig weld, i would be set.
Watched a video of a guy welding panels onto a ford truck with stick welder.
Used to gas weld, that was the go to 30 years ago.
My new mig still needs some figuring out.
