ive seen people use the cut thru both pieces method but ive never done it...I put my patch over the area and mark around it with a sharpie...and then cut inside the line on the rusted side....then I sneak up on it fitting...if I was gonna cut thru both pieces I think id tack weld it together to keep it from moving and use the thinnest cutting disc I could find...ive got some .030 discs

on this cab corner I had to build the whole thing as they don't make patch's for it...with no access to the backside I had to put a backer strip in it where the seam is so I left a little gap so my weld would bond to all 3 pieces...thought it turned out decent considering im not much of a body man
