WD 40 is a good WD (water displacer). But that’s as far as it goes. CX is a better lubricant and penetrant while protecting for a much longer period of time.
After a while WD 40 gums up to seize items that worked before and forms a film that becomes hydroscopic, resulting in creating rust. WD40 is also very flammable, in fact explosive, as you can start an engine with it.
WD 40 works great in starting your gasoline powered weed eater. But for long term corrosion protection you can not beat CorrosionX. Simply the best.
