Great work there, some years ago I did a restro on my truck using lead 20 yrs later still no issues, I used all metal to slick everything down, rust encapsulate then epoxy primer and emron paint.
Thanks! Yeah, I've always had great luck with lead. I know a lot of people have a negative opinion of using lead, so I'm glad to hear you had a good experience too.
I understand how you want to make the surface super clean. But when you add the tallow to the paddle, what keeps that from contaminating the solder? Do you have to clean off the tallow repair area afterwards so primer and paint will stick? When you go to file it, are there different grade files needed, or can you get by with one like that 8 tpi files. Do you feel lead is easier to work with over the plastic filler?
I know it sounds counterintuitive, but the tallow doesn't cause any contamination issues. It may surprise you that some of the old timers use bees wax or automatic transmission fluid instead of tallow! It must be a thermal/chemistry thing. All I do after applying the lead is rinse the area with a solution of baking soda to neutralize any acid left by the tinning flux. Then I file/shape and follow up with one more baking soda rinse, W&G remover, and then epoxy primer. I don't see the need for any other file than 8-10tpi. Lead is definitely NOT easier to work with in terms of shaping than body filler, but due to the potential risk of being able to see the seam (mapping) later down the road, lead solder (or a welded patch across the seam) is the better option here (IMO).
Great video!! I did some leading once about 45 years ago but it was becoming unpopular because of lead poisoning but I wanted to learn it. I don’t remember being concerned about panel warpage back then but watching what looks like so much heat being applied looks like it would.Is there any concern for warpage?
Gday…although I have never applied lead to a motor vehicle and there is more than one way to skin a cat. I have soldered a lot of specialty metals air conditioning for specialty clients. I was always more successful in managing my heat of the material rather than your this of heating the lead then applying to the metals. I admit I was more have m lead application to flow rare than build up so thick but if this helps great… if not we still achieve the same outcome al the best
With all the attention to detail and good reasons to avoid filler, why wouldnt you make the body lines out of lead since you're literally right there working that area, so those channels are clean and solid? Seems like it would be the closest to OEM, more durable, easier, less time consuming way to do it?
That's not a bad thought. Lead could probably be used to create the roof skin/quarter body line, but I chose to use VPA instead. As I mention in the video, VPA is a much better option than fiberglass/all metal. I opted not to use lead for a number of reasons 1) lead is harder to file/sand/shape than VPA, especially on that type of body line 2) managing the heat and melting lead while getting a crisp body line can be difficult 3) because the VPA filler is sitting on top of the lead filler, there's little to no risk of mapping due to different rates of expansion like you'd get if the filler was adjacent to virgin metal. Thanks for the feedback!
Just enough heat to get the tinning flux to react with the metal and then to melt the lead. Extreme heat would result in discoloration of the metal and warpage. It’s important to keep the torch moving.
I love that people are trying leading. It was definitely an art when I was taught.
It’s kinda like man discovering fire now.
I've seen too many problems with trying to use modern fillers in quarter panel seams, so I turned to the art of lead soldering as an alternative.

Nice job i really enjoyed this video
Thanks For watching!

I have used the all metal on my cutlass and I never had that problem and my car was jet black what I did was primed it before I al metal it

That seems like an extreme amount of heat on a panel
