Have any of you guys used anything to prevent corrosion on them? I have been having a problem with a distribution block corroding where the wire goes into it and preventing connection. Would any of these work?

Im kinda leaning towards the penetrox from the description.

Is your electrical exposed to the elements?? Don't think you want something for aluminum.....auto terminals are usually tin plated copper....try a simple di-electric grease available at auto parts store.

Yeah.... i try to mount that stuff away from the elements.
eh kinda. They are both mounted inside of the frame rail. The main thing ive been having problems with is the distribution block getting corroded inside of where the wires go. The outside is turning green like a battery terminal would.



cat, dielectric grease is non conductive so that wouldnt help me any.

EDIT: think it could be cheap material be causing my problem more than the elements getting to the connection?

pick up an empty electronics box from radio shack or other electronics supply store. cut some holes in the sides and mount the distribution block inside the electronics box. That should help a great deal. The corrosion is a chemical reaction of the two different metals reacting in moist environment.

actually, this is what dielectric grease is for.
its not supposed to be conductive.. but, it also doesnt stop a connection coated in it from connecting.

by coating the terminals in dielectric grease, you protect it from the elements, stopping the corrosion.
its used all the time to seal electrical connections in boats, planes, houses, industrial equipment, etc... anything that has open electrical connections that need to be protected from the elements.

that said, it does wash off, so you cant just glob the stuff on there.. usually its applied to something, then some weather resistant cover goes over, like a rubber boot.
