As sydster mentioned, M20 contains mild cleaners and functions like a AIO cleaner wax. It is composed of synthetic and natural ingredients. I like this product a lot. M21, on the other hand, is a 100% synthetic sealant. I have never used it myself, but I understand that its look is very similar to NXT.
