white E93, rear end gets dirty too fast, any tips?

Seems like this car collects dirt better than my vacuum! I just finished clay barring, polishing and waxing and yet black dust still clings to the rear bumper and trunk after only a few miles. My friend has a white 350z that doesn't get anywhere near the amount of dirt on the rear end. I'm thinking that it has something to do with the shape of the rear and the air flow. Has anyone successfully lessened the dirt by adding a spoiler underneath their bumper?

I'm going to try spraying Nano Diamond Shield on the car to see if it repels the dirt better.

It's most likely the static charge from the wax you are using. Switch over to a synthetic sealant instead of a carnuba wax.

+1.

Synthetics are designed to repel dust and dirt, whereas natural waxes have a static cling to them. Also, sealants last seemingly forever compared to waxes.

It also depends on what wax you use. Some are dust magnets and some aren't. My Zymol Glasur attracts less dust than my BFWD sealant.

You could consider coating your car with Gtechniq Exo v2 or cquartz. I have Exo v2 and it seems to repel dust really well. I have not tried cquartz but the slickness rivals exo from what I've read and slickness is the key to attracting less dust.
