    I know this is an old thread, but I've seen "old timers" use O/A combined with wooden paddles/leading and the results are most professional, bulletproof, plus you don't have bondo all over the place.

      Yes--I've done that. Used tinning butter, lead, and a carburizing flame. Took me a LONG time to get it right-it was about a 3" ding in the middle of the hood of my old Dodge Dart. Expected bondo would come loose from opening/closing the hood since I planned to keep it a long time. Had to be very judicious with the heat to prevent warping. Worked out great and was just like new when I finally sold the car years later. I think I still have the wooden paddle I made around the garage somewhere.

        I have a couple of old pick em up trucks sitting out in the field (restoration candidates) --- the metal is so thick on those oldies it only gets light surface rust. Plan on taking a class in leading to learn the nuances -- seems like the absolute best way to go on a restoration.

          Leading requires tinning acid, keep it out of any seams. It is junk in my opinion, and that's 40 years in the auto body business. It detaches, cracks, and causes huge rust problems in seams.

            Now that's an interesting comment since plastics / bondo were only introduced in the mid 1950's -- EVERY car built before that (and there are millions still out there) used the leading process to assemble cars.

              Hello I am interested in this article, about tinning and leading. I found a video at Utube by Mr.TIG, whose videos are always my favorite. Is this the way and work you are talking about here;

              Incidentally I am now learning alu and mag welding with TIG, but as far bigger gauges of steel sheets I prefer Oxy-Acetylene gas welding.
              Thanks,
              Chy

                Yes. That's the process. And that particular application is a good example.
