RestoFinish Tinning paste is a careful blend of tin, zinc, lead powder and acids. When it comes time to restore a vehicle, lead has its place in an authentic project.
When heated Tinning Paste creates a very thin coating of lead to allow correct adhesion between the existing metal substrate and new 30/70 lead filler material. Tinning paste (also called flux) can be spread with a brush or cloth then slowly heated. Once heated, the metals will bond to the steel and leave a smooth shiny surface.
