No problem, when you start practicing (go to the local metal supply and buy rems). Practice buttons, just a quick start/stop. Most make the mistake of trying to weld these panels continuously, they won't take it. But if you make a button and then weld between them and skip around you will not melt through as easy and you can control the warpage. Practice will make perfect. As I said in my earlier post these panels don't just drop right in they will need some careful fitting and the occasional filler piece. You can do it, measure twice and cut once.
