You have gotten great responses so far. Things I've learned about caring for a black car are...
using 2 buckets and 2 wash mits very gently
using a leafblower to get water out of the diffucult to reach door handles, mirrors, rims, etc. which will later drip water down your dry car
using a waffle drying towel to finish off the rest that will not scratch a CD
using Meguiars Deep Crystal step 2 pure polish ( available anywhere) along with whatever other products you like- nothing else has ever given my paint such a deep, wet look. I just wish it lasted more than 8 weeks.
You should not really need a PC for a while if you are careful not to cause swirls in your new paint.
Black is the most difficult and rewarding color to deal with.
