Sealants and waxes don't protect against physical damage like rock chips. They might deter light swirling, but not by much. You and I are both lucky to be in SoCal, where, I know this is hard to believe, but our roads have far less rocks and other debris on them than a place like NYC. New York roads has sand, rocks, and salt all over them, primarily during the Winter months thanks to snow plows spreading them everywhere. Our roads in SoCal aren't perfect, but they're much more forgiving in terms of chipping. A family member had an E60 M5 w/ a clear bra that looked like it had gone through a sand blaster after only its first winter.
With that said, my favorite sealants are Chemical Guys JetSeal109
and Menzerna Powerlock. Both give fantastic long term protection against most of the elements outside of rock chips.
Something I wanted to throw into my previous post is this clear bra debate is, in my mind, similar to the case/protector for phones debate. With beautiful devices like the iPhone 5 or Galaxy S3, do you want to hide their gorgeous appearances w/ a distracting and ugly case? A lot of people do apparently, but for me, I'd rather see my phone in its natural state than covered with plastic.
