Glanz to SV Blau Weiss...back to Glanz

I have, the issue is, when I have the SV over the Glanz, the same issue occurs if a rain shower comes along....the dust, pollen and water marks love to "hang out" in the carnuba ressy left behind.
The Glanz just seems to work well on my imola red. Also....Menz PL does a great job too, I just found that Glanz lasts longer.
