Rear Diffuser People Question - Rear Bumper Dust/Spray

[mp25]

Hey, with all the rain lately I have been getting a lot of the mist/mud residue on the rear bumper and gate. Much more evident and thick than on my prior MDX and probably due to the shorter proportions of the rear gate and haunches. Having carbon black paint doesn’t help either, but just wondering if the folks with the diffuser and wings noticed any "less" accumulations with that than without. Might be worth the install to not have to cringe after parking the car and walking past all that dirt and potential paint issues later.
