Bushveld,
Watching this brought back memories. When I was 17 I purchased an old beater ‘29 Model A coupe whose doors were rusted. I brought them in to my metal shop course in High-School along with some plastic fillet as a class project and proceeded to use the plastic. The teacher said no, you need to do it the correct way: tin the metal then fill in with lead. Went to the local auto parts store and after several trial and error learned the old time way. Still have some thick lead bars somewhere in the garage.
A good thread.
