Since they like to shovel the salt out on the roads around here, I had this company treat my new truck.
https://www.krownstl.com/ I have hear good things about that brand, originaly in canada, looks like there showing up in the US. I like the Idea that they dont spray black tar all over the car.
Reasonably priced as well. $130 to $150 depending on the size of the vehicle. Looks like only one location is the US, in Saint Louis.
I used to swear by that stuff when we lived in North Dakota. Was pleasantly surprised when this one opened up in St. Louis. I get my daily drivers done now.
They are actually a local snow removal/plow company that started using Krown on their own salt fleet. They liked it so much they opened a franchise to do cars in the off-season. I think they now have a contract now with MODOT.
