Mowing 60 " MMM paint

[duster]

I am looking for a durable paint to paint the blade side of my MMM on my BX2200, I have tried a number of rust preventive type paints but they just are not long lasting to the harshness of a mower deck.My question is what paint is good for this area.Thanks

I have heard of POR-15, as a coating, researching it now also.
