looks better BUT all them over lap joints and traps have to be clean from loose rust and any grit from sanding the oilpan .so i would fill the pan with water and molasses let sit fill past sump longer the better then take the pan set it so it will not fly around and wash it at the car wash or power wash it blow dry with a blow gun till dry and nothing comes out of the seams over lap s. i have a blow gun with a steel tube tip thats bent in a 90 so i can get at them over lap joints were they weld the sump on and blown clean till dry
