Dirty Rear End

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

I don't have this issue on my 2007 Yukon XL, at least, certainly not nearly to the extent that you do.

I don’t believe there’s any way around it. Can apply a good hydrophobic ceramic coating (or a good wax) so it’s more easily removed with a washing. And I hear you. This happened after one bird watching trip around some dirt roads...

Might try some of these and see if that helps the air roll down better. Turbulent flow changes direction better than laminar flow.

Hey, I hadn’t thought of those, great idea, will investigate further Thanks!

You can donate your money to attempt a cure, but I’ve never found one. It’s just a fact of life with any square bodied vehicle.

Oh man,
I feel your pain for sure,

I had something similar to this on a 99 Yukon. It directs the wind flowing over the vehicle down the backside to reduce the spray kicking up from behind. This one is a GTS® - Tape-On Aerowing™ Rear Window Deflector.

dam man give it a bath. we just had a dust storm here in Abilene, TX. I live in the city and my 2019 XL gets just like that.

Yeah, my 19 Premier does too, and it is a full days work to get her spotless again.....
