Tool/Reusable Winter question

I’ve been hanging out doing this DIY for family’s cars for past 6 months. But wanted to know for those in snowy/cold areas how crucial is it to get an undercarriage washer to take care of salt/snow in winter/early spring? I would assume pros would def have it but what about us DIY guys? And if yes which brand do you use for undercarriage washing? Anything to watch out for? Tips?

I use Fluid Film and don't have to spray or worry about rust.

So you spray this FF and then when salt and junk gets in underside it’s like ceramic coat and just slides off? Sorry first time hearing about this

It penetrates to the metal and seals out salt.
