Being somewhat structural you could go with 18 gauge which is harder to form into shapes but is easier to weld. Since the pieces are mostly flat it shouldn't be that hard. 22 gauge would be too thin for a roof, I personally would never use that gauge, and butt welding would be tough. You might find some 20 gauge on your car if you mic around different panels. Ford used 19 gauge throughout most of their cars in the 60s. I have a few flat patches on my Park Lane and I will use 18 gauge I have.
1 vote for 18 gauge. So we're thinkin 18-20 gauge?
