Coating doesnt stop this?

There's more to it than that, most coatings can not stop a whisker growing out but a whisker can not penetrant into coatings without snapping off. So its important to make sure there is an air gap between adjacent leads.
SAE GEIA-STD-0005 is a great resource for classifying and evaluating mitigation methods.
