I am having staining happening on my 2018 F32 440xi's rocker panel. It is a white colored car and I do have xpel fully wrapped. I can wipe it off, but this is constantly happening. Here is an image of it. Check the bottom left corner of the image.

I found an output on the door where water is draining out. Anyone else have this drain on their door as well?

Everyone does, otherwise water that enters the door by getting past the seals on the windows would stay in the door. It's likely that anti-corrosion treatment sprayed on the inside of the door isn't fully cured yet and that eventually the staining will cease.

3 years in and it still happens for me.

I never saw it on mine, but my color is Midnight Blue.

I have never seen this before in the different cars I have ordered over the years. I had my car wrapped with xpel so it would look nice an clean all the time, and this just ruined the whole point of getting the car wrapped. Car is 6 months old.

You use xpel to keep the paint from being scratched. It might be somewhat more resistant to dirt adhesion, but not that much. That's the job of a sealant. I sealed mine within a week of getting it, that might have something to do with never seeing anything like that.
