I cant for the life of me remember the name of the product to use at the joints of a aluminum antennas to prevent the joints from seizing up in the weather............I dont know if this would work or not if anyone has a opinion on using bulb grease as a substitute. This thought just came to me about the blub grease. I have narrowed it down to 2 antennas the Maco V58 or the Sirio GPE 27 5/8 would like some opinions on them both
