I have a 2014 MDX with the nice color, Fathom Blue, that has 72K miles and has been on multiple coast to coast road trips. I'm diligent about parking out in the boonies, on an end, etc. (but I don't take up multiple spaces), my wife careful but not as careful as me, and fortunately have no door dings as a result, but it does have plenty of hood hits from debris and a couple of side hits from debris - all surface hits without any denting. I've used the Acura touch-up paint on a couple of the spots but most of them I leave as-is because the touch-up itself can be noticeable and sometimes makes it worse than the original ding, but other times it makes it better. Although I reserve my garage space for other cars so the MDX sits in the driveway (in southern California), the vehicle still looks great - practically brand new inside and out, but a close inspection of the hood will reveal dings.
A side note - my last couple of SUVs had hood deflectors which helped tremendously in protecting the hood from the unavoidable road debris but one isn't made for the 3rd gen MDX - at least not that I could find. Some people wrap the hood, the front end, or the entire car in plastic wrap to help guard against dings. I chose not to do that even though I tend to keep my vehicles a long time but again, this one still looks and feels great after having it for 7.5 years but I know at some point I'll sell it and buy another vehicle then all of these imperfections will go to a new owner and I'll start accumulating new imperfections on the newer vehicle.
The good thing about a vehicle with some road experience on it is that one doesn't get quite as worked up on the next debris hit since the vehicle's already been initiated in that regard.
