If you wil read the post, you will see where I put the lube on the PLASTIC lock ring and plug, NOT ON THE CONNECTIONS. Those are always wire brushed to clean as necessary.
BTW, a major electric switch manufacturer did a study years ago and found the petrolium jelly is just as effective for corrosion protection and contact lubrication as any of the "so called" contact lubricants. I have used it for years on low voltage contacts, such as the TV plug. YMMV
