Bee's wax

Way back when I had a bread pan with about two inches of bees wax in it with my auto body tools. Heat it up with the torch a dip the paddle in it when doing lead work. I wonder, does anyone do lead filling anymore?

AI Overview

Yes, "lead filling" or lead loading is still done in a niche capacity, particularly in classic car restoration and some custom metalwork, though it is rare due to the prevalence of modern materials and health/environmental concerns about lead. The original use in vehicle manufacturing has been replaced by methods like riveting, bonding, and welding, and the practice is avoided by most body shops due to its potential for corrosion and incompatibility with modern primers and paints
