Jerry, don’t get discouraged when the guys choose another way. I personally have always used the one at a time method. I have read your companion cylinder process over and over and each time I come away impressed but still haven’t tried it. I think many of our readers are stand out in the driveway, with a set of Chinese wrenches, mechanics and may be a bit intimidated by the process. No offense to the shade tree guys I’m pretty much right there with you. Hang in there Jerry.ðŸ›
