How much rust can under-body spray stop?

these newer autos have a better protection on them. urethane paints, galvanized metal factory, rustproofing in key areas. all these help to keep these newer autos rust free, not like 20 year old cars.

I think most cars have a warranty for rust that's at least 12 years or more.

Easier said then done.Head down to the local car wash on a salty road when its 10 degrees rinse your car off head back home on the same salty road.No win situation.LOL...

In an argument to that, It also seems that they are making both the frames and body out of many, many, smaller & thinner "parts" that can be cheaply pressed, all sandwitched together and spot welded, I think as a result of available robotic welding. All those seams just suck the moisture right in and whatever galv. might have been on the metal is ruined around the spot weld. There seems to be many more inacessable areas also that can't be inspected or cleaned/treated in modern vehicles. And don't get me started on that dang foam in body void's, that never ever dries out!
Currently I'm betting on Fluid Film and weekly, mostly underside washing. For $38 for a gal. can, and their $24 sprayer, a gallon of FF go's a long way. The vehicles I care about stay in the shed all winter

Luckily for me I can rinse them off at home with wood heated hot water. "Just throw another log on the fire." Jon

Wish I had that option.

This has been discussed here before, and relatively speaking, no, you don't have very salty roads there at all.

You do realize how skewed that data is right?? Surely a man of your experience does.

I think most car washes recycle the water. In some areas, like California, it's required by law. They filter the water and I think they use fresh water for final rinsing, but I think it's likely your local car wash does recycle.

Nope.

Look we all understand that if it snows in Missouri, you guys probably put salt on the road. The point is that is only happens once or twice a year for you. Up here in the rust belt we cake our vehicles in salt for 3-4 months of the year. It's brutal and if you haven't lived here, you probably don't really understand what we're talking about. This isn't to discredit your opinions on prevention, but, c'mon. It's not at all the same.
