I had to retrieve something from under my Jeep the other day and I noticed that there was a lot more corrosion than I would have expected for a vehicle with less than 12K miles. Further inspection led me to look more closely at the welds, almost all of which are corroding. I’m no welder but I can solder jewelry and these welds look pretty awful to me. Some are off-center, others very porous, some look like they’re cracking, and some are not even completed. How bad is too bad?
