I have a few small patches to do on the floor pan of my 54 pu. I have a bunch of 16ga. steel non-galvie laying around. The post that I have read here and else where all say 18ga. for patches...would I be breaking some kind of restoration rule by using 16ga.? Its thicker and thus can be MIG welded at a faster rate. I plan NOT to cut the midly rusted areas out but just overlap the patches and do a seal weld around the perimiter and some in the field of the patch then grind/flap disc smooth....any thoughts...ideas...constructive criticisms..THANKS, Steve
