No outer body panels are 18 gauge. More like 20. You and anyone else can get a caliper and measure.
Gas is less hot than arc, but regardless, you need to planish and on a fleet bed, you can't. You need really tight/cloe fit to do good gas welding, and actually want pretty close fit w/ mig/tig. Long ago, people would gas weld and planish while the weld was still red hot (hammer weld). This knocks down the weld and expands the weld that would be shrunk by the heat. It seams this was done with filler rod.
