ground wire protective coating

[cloonypan]

Hello,
Please refer the attached pics. I am looking for a transparent coating material to preventing the ground wire rusting as attached. If possible, is there any recommended? Thank you.

First, I think you have to replace the copper lug with other compatible to steel contact-for instance Burndy or equivalent. Second, if your Electrical Code-as NEC does, for instance-allow to use an insulated grounding conductor replace the actual bare conductor by a pvc insulated one.
As another option you may keep the actual conductor and cover it by a RTV Silicon Rubber layer.
See-for instance:

The colour could be a problem in order to meat the Code requirement.

I see either insulated copper wire or braided straps made of tinned copper for similar bonding jumpers.
