Yeah mate, that is the one the MX5.
I did not mention the number as I wanted to check but I knew it was in the black can.
Super junk auto carry the cans. The dark blue can is the standard INOX and that is good in its own right, the light blue can contains lanolin and is good for rust forming conditions and the black can MX5.
Yes, there are plenty of types of INOX and they are all good products.
I used to work in a tractor dealership and we sold the product and used it in the workshop.
It is that good I still use it even though I have to pay for it now
