Re: Firewall Swiss cheese-What to do
Find some scrap sheet metal the same thickness (Junk hood, door, fender and cut some pieces out of it and practice welding them back in. You don't even have to cut it clear out just cut a slot, clean the metal around it with a flap wheel and weld it back together until you figure out the settings and gain a bit of confidence.
The one screw up that happens all the time is that guys try to weld too long a bead in one spot and end up warping the metal. Very few of us can honestly say that we have never done that on a rig at one time or another. It's called learning experience but you can also learn from those of us who have already made that mistake and just put short tack welds around the patch, let it cool and tack some more.
LS Fab makes some nice bead rolled panels but they aren't all that cheap. https://lsfab.ca/product-category/5559/
