I am 16 years old and really admire experienced bodymen and mechanics. I know that leading is a lost art, and I hate most new technology. I like to do everything the way it was done back in the day. A few weeks ago, I redid the leading in the A-pillars of my '39 Chevy truck and used a torch and the solder you use on copper tubing. It came out fine. Is this an OK lead to use? If not, no biggie, just melt it out! Thanks.
