Well said, coopernicus. I definitely agree with you on the under-carriage wash, that is something I really appreciate as well. Even during the warm months, after like 3 or 4 weeks of hand-washing, I take it to my local auto wash just to get the under-carriage washed. As for the acid they spray on the alloy wheels, that stuff only hurts your rims if they are not rinsed properly. Fortunately, auto washes are designed to rins the wheels extremely well, so it generally should not be an issue, but like you, I am scared as well.
But when it comes to waxing and polishing and generally detailing my car, I only trust myself.
