We've all heard it I'm sure, "If it moves and shouldn't, use 'Duct-tape', if doesn't and it should use WD-40." WD-40 is a water displacement treatment. If you are protecting metal from the ravages of water, WD-40 is good. If you want to loosen a rested bolt, then Liquid Wrench is better and faster. If you want to lubricate, then some kind of petroleum or synthetic lubricant is the choice. The major cause of problems with our antennas is dirt. I is attracted to the oily resedue left by petroleum based lubricants and causes wear and that leads to looseness. The best thing we can do is keep the antenna clean. Eliminate the buildup of dirt and grime. I suspect that the clean dry antenna is better than one with oily residue. ....bc RCSE-List facilities provided by Model Airplane News.
