I don't really see that as a comparison, per se, I see it as a replacement chart. So if you are using a particular Meg's product, and you want an FK product to replace it, you cross it. Why do I say this? Well, for one, they list 3 comparables to #36 Hi-Tech Wheel Cleaner, #717 HD Cleaner, #117 HD White Wall Cleaner, and #583 WAC Wheel Acid. Certainly, a Wheel Acid isn't comparable to #36, which is pH neutral. What they are saying is, if you are using #36, you can use one of those 3 products to replace it. In any event, I would take the whole thing with a grain of salt, marketing info from FK, printed or phone/email, is more like propaganda and hasn't been known to be the most accurate.
