Norseman corrosion

[Robbie.g]

I'm no expert, but it looks to me that the cone is stainless as there is no signs of corrosion on or under it, and the wire ends are clean (not the reason for the staining). But where there is some staining is on top of the sealant on the outside of the fitting, the part exposed to the elements. It seems that the sealant has done it's job inside the fitting, although the inner strands near the top of the fitting, do appear to have some staining?![no goo] My feeling is that the staining is tracking down the wire from above, as opposed to beginning at the fitting and travelling up! I would agree that contamination is the cause, but the origin i feel is from the outside/aloft.
i thought that Stainless Steel, was that ...stainless,[not stainfree] and staining differs from corrosion especially that of the crevis variety.?? i'm very happy to be corrected on this definition
There's me 2 cents.
