Battle the water spots?

My new tacoma is the first black vehicle I've ever owned and I quickly found out how bad the water spots are with the hard water here in Los Angeles. I still rent apt. so now I go to the do-it-yourself power sprayer washes at night for two reasons: 1) they don't allow "bucket washing" but at 11pm it's not busy no one really cares and 2) it's cool and will stay wet until I start drying.

 

I thought that the water spots on mine were permanent but I got 99% of them out. The acid rain from the volcanic gases here kills paint and quickly at that.

So basically I used clay bar (had to apply a lot of pressure on the clay and use lots of the quik detailer), swirl remover, polish, 3 coats carnauba wax, and 3 coats of synthetic wax/sealant to top it off. It was a LOT of work but at least my paint doesn't have those ugly ass water spots now. The key for me seemed to be pressing kind of hard on the clay bar and making many passes over the paint with it. I just hope that it didn't remove too much of my clearcoat
