Robin, I have been using wd-40 since 1975 as a starting substance, and had instruction on it's use back in Kawasaki Tech Training School in Edison, N.J,in the 80's and 90's, where I was certified as a trained technician by Kawasaki, (1 of 5 certifications). I haven't had any other experiences but good with wd-40, as a starting substance and water displacement. What is the new and improved method for starting substance, with a lubricant with all your research? I am always open to suggestions and better methods.
