Holy cow building a car from scratch takes a lot of this stuff. This is the first game i’ve ever tried to build a car. I’m scrounging every house for light disposable batteries to craft the rods. Fortunately most houses have at least one in a flashlight. Is there another good reliable source for welding rods or wire?
According to the HHG, welding rods and wires can be looted with high confidence from megastores, steel mills and some garages, with low confidence from light industry, parking lots, malls, pump stations, farm supply stores and other garages.
Light industry also sometimes has brazing rods, AFAIK, they can be used too.
