I don't like the auto darkening helmets. Every time I use one I burn my eyes. I have almost pure night vision so my eyes are very light sensitive.
I have used both MIG and TIG, TIG is easier for me on thin panels. If you can oxy/acy weld you can tig weld. You have more control of the molten metal since the flame does not imply any forces.
Practice Practice Practice is what it takes.

Sure TIG is better, but Duke has made it clear in several threads that he is on a budget. MIG works great on sheet metal as long as you fit up well and leap frog around with a series of tacks instead of welding a bead.
I would LOVE to afford a TIG setup for my home shop, but I can't justify it either. I can do anything I want with the MIG. In fact in the past I welded sheet metal with 5/64 rod and an old Lincoln Tombstone. After that my MIG welder was heaven on Earth on sheet metal.
Duke if you are really strapped, you can get by with the flux core if you will steel brush each tack before getting near it with another. This will be time consuming as all heck as compared to shielding gas, but it's better than piling up on the couch in front of the idiot box due to lack of funds.
Keep on workin' on that truck. Funds or no funds there's always something you can be doing.
Good luck,

A torch heats up a larger area, mainly due to flame angle. With TIG you can actually use less heat than MIG. I've used both, each have there place. If you fit it right you don't even need any filler metal. I don't own a TIG, had access to one up to 3 yrs ago. I have an 30 yr old air compressor I'm going to be forced to replaced soon, it's starting to stink when it runs, so the motor is getting close to going. I've welded a AL coke can with TIG before. You have that kind of heat control. I use to be able to weld AL with a torch, which I may end up doing it again to make a gas tank. Not the low temp brazing rods either.
But I'm not suppose to weld any more due to my implant. But I do some, but I have to route all of the leads away from my body.
Since he's on a tight budget, look at the 3M adhesive. All you need to do is glue in a frame then attached the new panel to the frame. Easiest way, NO Heat to warp anything. 3M says its 10 times stronger than welding, which it can be due to surface area, lap joint design.

TIG, used correctly, will concentrate the heat at the weld, minimizing sheet metal warpage. I would love to have a TIG rig (poetic, huh?) But even if I had a TIG, I just feel comfortable welding sheet metal by leap frogging around with my MIG using shielding gas. For me it's just sure fire.
