What about the car washes. I use the Esso touchless basic wash, does it wash the underbelly of the car?
you haven't rust proofed your car in 7 years? WOW.
I'm almost as bad, but sorta caught it in the bud.
First before you go, either wash the underbody, or, I believe at Krown, once up on the hoist, they will shoot the under belly with some warm water...(i think).
Washing it regularly, on those nice days during winter, isn't a great idea.
It's actually bad, if you think about it, you're just giving more fuel for the rust to work.
That's why I laugh at people lined up for those touchless car washes when there's one nice day during the winter months. If any salt got under their car and stuck, mixed with water, guess what...?
It's never too late after 7 years of NOT doing it, but just don't expect a perfectly clean, rust free, under body either.
Oh and after rust proofing, don't wash your car for at least a week.
If it rains, whatever, no control over that, at least it's not active powered water shooting up at the rust proof, it's just water being kicked up from the tires, not that big a deal.
