Hello,
I have been using car wax for lubricating the moving parts of my planes and its been working great. I use both the paste and liquid types depending on what I need to do. I've used paste wax on pushrods that don't slide freely and it's a night and day difference. I even have used a few drops of liquid wax on my wheels and axels and it is amazing how much easier they spin. The best part of all is it doesn't attract dust once it has dried and you can't seem to over do it. Jeff
