When I was in highschool, I used to work after school "restoring" / repairing VW beetles. Welded countless floor pans and rockers in with oxy fuel torch. Replaced alot of engines as well. Probably the easiest vehicles to work on I've ever touched.

Oxy-fuel was teh quickest to weld the pans in as it will tolerate alot of dirt and poor prep. a "repair" job got alot less time / attention than a "restoration" job. Brings back memories of laying on my back having hot blobs drip on me and having a guy up top with wet rags for when some seam sealer or similar caught on fire inside. :-)
