Spectra tanks are Ni Terne coated.
What's the process for that Scott? I take it that it involves at least a Nickel coating.
Stolen from Team Camaro: - http://www.camaros.net/forums/showthread.php?t=207355
The annealed cold-rolled steel sheet is first processed to apply a thin flash coating of electrodeposited nickel, and then it's given a hot-dip lead-tin alloy coating. The nickel base coat gives Ni-Terne steel an extra measure of corrosion resistance compared to U.S. Steel's regular "Terne" steel sheet and also compared to traditional galvanizing, which isn't readily available anymore. It should also be pointed out that the Ni-Terne coating protects both interior and exterior surfaces of the fuel tank from surface corrosion.You have 2 different types of "galvanizing". Just by doing a little google searching I found a couple of videos to give a better understanding of the processes. Cold
- which can be done electrically or in other cases as paint which is enriched with zinc to give it that added protection. Cold Dip GalvanizationPros
- cost, and applicationCons
- looks like paint (paint version - I am still working on trying to perfect this process along with the electro process)Hot
- which is where the zinc (or lead/tin as mentioned previously) is heated until molten and then the part or steel is submerged slowly and stays there for several minutes and slowly raised out and a layer of zinc is bonded to the metal. Hot Dip GalvanizationPros
- it will look factoryCons
I am currently experimenting with the two cold processes mentioned above and trying to locate a company locally for pricing on "Hot Dipping".
Where is the big red Gorilla on this one
? COOK where are ya buddy, aren't you the plating guru around these parts??
I am certainly NO expert. I enjoy learning processes and how to accomplish them myself and for others if the opportunity arises. My apologies for not seeing this sooner. I was working on my car all weekend getting the headliner installed along with the diff ready to go back under the car and removing the tank for this same process as mentioned by the OP. If I have missed something on the processes or explaination please correct me so everyone can be educated. Thanks, Darrell
