The only reason I'm doing it is cause you upped my confidence in doing it with your suggestions that makes it easier, the flanger won't fit, it's cut uneven due to a last minute change of plans, it's in an area that will hold the metal against warpage, and I'm filming it, so there some ego involved for sure. Most times I'd just play it safer and flange, and not feel an ounce of guilt about it.
flange(overlap) panels rust.. big problem.. maybe not in dry areas.. but I'd run from a shop here that was going to flange/overlap then weld.
