I seriously don't thing anything works well enogh on your machine Massey; the various spray can stuff I have tried works much the same, minor differences and one thing can turn out to be just the right thing one time, and the next time another product seems to make the difference. Either way, in most cases it is patience, applications, and multiple reapplications that does the jobs. Some of these products contain different ingredients, and when those are identifiable we can switch product after a while. Called, lubricant, penetrant, bolt-off, water dispersant, they tend to be much the same stuff with just one or two differing ingredients.
