I bought some, decades ago. At the same time, I bought a tin of Bee-Seal, a softened bee's wax preparation.
The BeeSeal turned out to work so well (smear it on and it seems to soak in) that I never did use the highly recommended Sno-Seal.
They both should be ideal in wet snow conditions. Here in the cold, the snow is like sugar, just brush it off.
You likely have regional equivalents which are just as good if not better.
