I keep my cars a long time. I'm pretty meticulous with winter underbody washes and I touch up the paint nicks and always keep a good layer of wax on it. So this summer I'm hoping to spend some time on the wife's 2011 RDX with some POR3 and I'm interested to find out where rust wants to grab hold. Other than the exhaust system (which I'm greatly disappointed in) where are the areas people have seen rust?

 

on the roof if u got hail dings

 

Good question, I have not seen much rust on ours. This may sound strange, but the only place that currently has rust on our RDX's body is above the license plate where the trunk release button is, there is a small amount of rust near that button.
