Hello everyone, I am new to the site and this is my first post.
I have a 1953 3/4ton GMC and have removed a panel off the cab and noticed the seam was filled with lead. I would like to refill the seam with lead but have been unable to find a body guy that could give me some help. I know that I am asking this question to the correct group of people. Please point me in the correct direction to get information.

Thanks
