RESTO FINISH TINNING BUTTER 500GM

DESCRIPTION
Tinning paste 5000 grams
Traditional lead has been used by early auto manufacturers to cover body joins and seams. At the time this was the only material available for the job. It has been regarded as the best method to do so, and in most cases has lasted the test of time. Later in the 1950’s lead was heavily used by the pioneers of car customisation and hence the term “lead sled” was then derived. When it comes time to restore a vehicle, lead has its place for an authentic project.
Lead is a filling material for areas on a vehicle that require it. Most commonly used on sections that cannot be metal repaired completely. It is perfect on pillars, panel edges, exterior corners and shut lines. Its strength is also ideal for door and panel edges that are vulnerable for chipping. Lead is perfect to cover over seams and overlapped metal; it will not show up witness lines or shrink in these areas.
To achieve correct adhesion between the existing metal substrate and new 30/70 lead, the surface must be “tinned”. This process creates a very thin coating of lead. Firstly, the metal must be cleaned thoroughly – this is best done by first sanding, then wire brushing the surface. The 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. The excess flux must be removed with a cloth. Any trace elements of flux will result in a contaminated job and eventually create bubbles and blisters in the paint work. The key to a successful tinning process is to start with clean metal, and clean again afterwards.
This 500gram tub of tinning paste is made from 50% premium tin powder. Simply brush on and heat.
