Keeping the Dust off the back of 4WDs

I had one fitted to the Patrol for 3 years and really could not tell you if they have made any marked difference.

We travel a lot of dusty roads with the 4WD club and I still get dust build up on the rear. They look good but not too sure how well they work.

I think in hindsight that I could have spent the money on something more practicable.

I have one at the top of the back door of the Prado. Before I put a full ARB Roof Rack on it was doing a good job of blowing heavy dust buildup off the back window on dusty tracks. Since fitting the roof rack the airflow is much more turbulent back there by the time the air goes through all that bar work and the dust deflector does not seem to do anywhere near as good a job. I have noticed several times the dust building up on the back window more than it previously did on similar tracks.

So yes, good things until you put a roof rack on.

The previous owner of my Prado fitted one. I don't have a roof rack (tow a trailer instead) and the dust wing seems to work quite well. I get very little dust build up on the back window / back door but a lot gathers on the bumper bar presumably because the redirected air blows the dust straight down onto the first large horizontal surface.

Have heard of great reports on these little units, but look a bit strange...Cheers

Thanks for the replies.

I am using a roof rack and the dust on the window doesn’t bother me, was thinking more of trying to keep the bumper area cleaner from an unpacking point of view when camping.

Looks like they won’t really do what I am after anyhow, but worth asking the question.
