If it's your daily driver, it will get door dings/scratches/etc, so use your vehicle to do something you enjoy and accept that you cannot protect her all the time.
I upgraded from factory subaru roof bars to the whispbars and they are much better. I leave them on all the time now. If you're worried about scratches, you can clearbra the mount areas.
If I can transport a PA12 on the roof of my STI, you're out of excuses.
