Stubborn bus bar
Bought a couple of small Insulated bus bars from AZ WindSun. It has 6 set screws: 2 big for AWG 1-14, and 4 small for AWG 6-14. Big screws are flush, small ones have button-head. Nothing special ...

A, You can brighten them up with aluminum polish but the only mechanical areas of consideration for conductivity are the bottom of the lug hole and the bottom of the set screw.
A. If the bus bar will be located in an environment prone to oxidation (seashore), I would use an antioxidant compound. The Noalox compound seems to fit the bill. I know Mex has his own favorite but have forgotten the brand name. I've been using Caig Deoxit Gold spray and for less severe environments, it works well.
I seem to run into these issues at times and it usually involves the plating of the parts. I guess the thought is that corrosion is easy to spot and interference from plating is a minor inconvenience. I'd like to put a screwdriver in the hands of these guys and have them work on these parts when contorted in a close space.
Good luck with the bus bars, they should work well now that you have them loosened.
