Clean no longer shiny

[Blkvoodoo]

so I pressure washed the roof, no soap, just blasting out the dirt in the rough finish.

2012 Flagstaff 625D, bought new, May 2011. the shine is gone from the roof, is there anyway to bring it back but NOT attract more crud ?

I know the crud in inevitable, and I'm not anal about cleanlyness, just like it to stay new looking for a while longer.

would a wash/wax type automotive soap work ?

I used 303 on ours a couple of weeks ago. It was very shiny, at least until the next windstorm, then it was covered with very fine dust. The static-prone climate we live in does not help to things nice and shiny clean. I used the 303 because it is a good UV protectant and, given the amount of sunshine and altitude (our house is at ~6,000'), we figured it was a good thing.
