Any of you have issues with your locking cap? For the last couple years if keeps corroding so that you can’t unlock it.... you have to spend twenty minutes working it with wd40 and the key. A white mess of corrosion usually comes out in the key, then I use graphite key lube.. but it still keeps happening. It shouldn’t be rain because I cover the bike religiously. Any ideas on how to keep this from happening or is the venting bad on the cap causing this to happen for some reason?
