Lead loading is an old body repair method that fills seams and small dents with body solder instead of plastic filler.

What is Lead Loading (Body Solder)?

It was used on production lines and in classic restoration. It bonds well and does not absorb moisture. It needs skill and heat control. Lead-free body solders are available as safer alternatives.

How it works

The metal is tinned, then lead solder is melted on, shaped and filed smooth.

Why it matters for your car

Lead is toxic; use protection and avoid breathing dust. Too much heat can warp panels.
