Solar: Add Anything to Copper Crimps & Tilt Angle for Panels

I have seen something somewhere recently not to use any goop in there like that, but can't pin it down at the moment. Was in one of the owner's manuals for something, not to use any of that red spray stuff you use on battery posts. Might not be the same as what you are asking about.

5 degrees to get run off, but the roof may already be at that with camber.
