So I came to notice that my 2011 M3 lock on my hatchdoor is rusting. Still works fine with no problems so far. I rustproof my car at Krown every year but not entirely sure if these areas get lubed up. I'm thinking maybe I should get something at Canadian tire and do it myself.
Anyone have any ideas to take care of this before it causes a problem? If not, I might even take it to a shop or dealer to have it looked at.
