Oh, I forgot. Some feedback. I welded the exhaust with a bunch of tiny aligned dots and I'm pleased to say that's it's completely shut and looks and feels stronger than I anticipated. Guess the metal wasn't as rusted through after all. I'm driving this thing as long as I can

Thanks for your help! And special thanks to Clearwater George for helping me realize I don't actually need an expensive welding helmet. No more safety snobbery for me.
