Brand New Lexus (2013 Es 300H) - Need Recommendations

[palermo22]

First, do I want to do anything at this point or should I wait a few months? I would like to use a wax (perhaps something like Collinite) to seal in the paint job but don't know whether to do it now (one week after purchase) or to wait a bit.

Second, should I used Collinite or Blackfriar Wet Diamond, Wolfgang Paint Sealant or something like Optimum Spary Wax (I read about all of these on various sites).

Also, whatever car I drive, I can never seem to get the glass clean without having swirls or cloudiness somehwere - any recommendations here?

I thank everyone for their suggestions.
