Undercarriage
I read a rather large thread about some guy who's truck broke down during a car wash. There was a lot of talk about undercarriage washes. What are your opinions on if it is pointless to do or not?

I get it done just to wash away the salt during the winter and road debris the rest of the year. I figure less salt and gunk over the life of the vehicle = less corrosion. I've never had a problem with it, and I get mine washed once a week.

No i think that was a extremely rare case. The pressure would have to be very very intense to cause any damage. Even spraying in the engine bay is fine as long as you cover the proper components that are covered in the owners manual. I was my truck once a week and have never had a problem.

It was MY truck that broke down in the car wash. If you read my thread, you will know that it was purely coincidence. My truck suffered internal engine failure after 20k miles from new.
Before then, I routinely got an undercarriage spray with no problems. When I clean the top of the engine bay, I avoid high pressure sprays. I usually use the engine degreaser and the spot free rinse modes.
