I took a welding class at the local junior college. One night a week for 16 weeks. Cost $100 in fees. Learned the right way to gas and arc weld. Just need to practice to keep the skills up. They taught MIG and TIG in the next class, which I didn't take. Bought myself a MIG, looked at some youtube videos, read a couple of articles and started welding. With a little bit of practice it didn't take long to nail it! I just fabbed up some quarter panels for my '27 roadster from scratch and they came out pretty good!
