Actually my statement can apply to anyone, but Wifes66, I thought that you were using the thicker gauge metal because of your limited experience and that you also only had a flux core only type of MIG.
It is easier to weld a thicker gauge, but personally I wouldn't want to use 18 gauge for extensively sized panels that are used on the exterior of the body. Items such as covering side marker light openings, yes, that's a good idea. It's a personal preference thing as I see it.
