Why does solder melt after plating?
For some reason after the part (s) have been plated many platters have experienced issues with the solder melting under the fresh plating from the heat caused by the polishing process. 90% of the time the new plating tends to develop bubbles around the repair. When this occurs, the shop must strip the new plating down to the base metal re-cleaning etc. for a second attempt. This has been confirmed by numerous chrome shops who’ve attempted to use soft solder for repairing pot metal.

However the quality of their achievement is the question… 99.9% of individuals who can successfully get the job done are gas welding it with a jewelers torch. But there’s a couple of problems that keeps this method from being an ideal process for welding pot metal. Pot metal has two inherent problems. The first is it’s a very dirty metal. This is apparent when it starts to melt. The second, much like aluminum it oxidizes really quick about 10 times faster! This only adds to it’s volatility. If that’s not enough throw it’s heat sensitivity into the mix and you’ve got your hands full! Pot metal is a beast that most won’t even bother with.
Can you soft solder a part?
The cost. Some soft solder kits are really over-priced for the average, person with no experience. Before you can perform a soft solder repair on a part you plan to have re-chromed, you must have the local chrome shop strip the existing chrome off the part. Otherwise if this is not done, the process of removing the old plating will cause the solder will come apart costing you more time or money.

What is pot metal and why is it so difficult to repair?
Pot metal is a smorgasbord of metals, zinc, cadmium, lead, magnesium, copper, aluminum, tin, iron and any other leftover metal with a low melting point. Low melting point is the key because what they did in the early 20th century was grab all the scrap metal put in a big pot and melted it. The the mixture was poured into molds. Smorgasbords of anything are hard to repair. Weld are usually done with like materials.
Why do pot metal pieces flake off?
Because pot metal is so porous a break may often results in small pieces flaking off. The problem is that those missing pieces reduces surface area. IF there is enough surface area, you can use our Filler to fill in the gaps from the flaked off pieces. Our Filler is a silica sand compound used to fill holes or gaps.
