You can use the Bliar but just know it may eat up the cutters fairly quick on the rust. try to trim back to the arrows and its much easier to remove the strip that's left. You can also use a small chisel to bust the seam after you do the welds. Just lay the plasma gun on the drip edge pointing toward the roof panel that's left and drag it around the top

fyi you should use some cutting oil on the Blair tool or the grease stick they have
