You really have to stay on top of Honda paint because it's the one thing that IMHO Honda is terrible at. Both of my old 80s Honda's paint job went to hell.
If you want it to stay nice, wax at least every 90 days, AT least. Keep the car washed too. I wish I had a garage to put my car but alas I don't. I use a sunshade in the car when I'm not driving it and I need to get the windows tinted to protect the interior a bit too.
