Protecting underside of car - good idea or not?

[roberte30]

Hi,

I'm considering getting the underside of my car protected with Dinatrol. I'm torn between it being a smart idea to protect the car and it being a bad idea as the car will be less original.

The underside of my car looks pretty good but there are some rusty bolts and the exhaust connector support is rusty. Appreciate I can replace those parts (and I will) but I lost an E30 325is to underbody rust so it's sonething I'm concerned about as I plan to keep the car for many years.

The firm I'm thinking of using is jrclassics (http://www.jrclassics.co.uk).

Welcome your thoughts on whether I should do it and any pros or cons. Would you be put off buying a car professionally treated in this way?
