I've learned too many times the hard way. Do not use W40 to stop rust. Pick up a $10 Canon fluid film at Napa. You'll be out by the road waving. The American Flag saying this is a breakthrough. Next, use it for a lubricant when drilling. You'll be waving the flag ten feet higher❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤😊😊😊😊😊😊😊😊
