About a year ago, I purchased the Basic Lead Filler kit from Eastwood. I wasn't sure if that was something I wanted to tackle. I thought about it, and figured the worst I could do was to overheat the hood (which was the body part I wanted to work on) and warp the crap out of it and ruin it forever. So, Why not?
The first thing I had to do was to brush on some tinning butter to get the lead to stick to the metal. I then heated it to cure it.
I used a propane torch to melt the lead and spread the lead while inadvertently setting fire to my wooden paddle. But it spread out pretty well.
Since the product is actually a lead-free solder, I could have used an electric sander. After trying it, I didn't like the way it came out. So I used the "cheese grater" that came with it.
After some deep burning in the shoulders, the soldering began to take shape. I was pleased.
