The product is T-9 by Boeshield, available at West Marine, Defender, Jamestown and other places. It is ****ing great around electrical connections, bulbs, bus panels, etc. preventing corrosion. It is safe to use around a fuse panel, as it will not conduct between terminals. A bit pricey at 15 - 18 bucks a can, but well worth it for the convenience and promise to do what it says it will. Also good on your reels guns, whatever.
