Rain is fine (not large hailstones though), just don't wash it if it gets dirty. It will take a few weeks for the paint to 'air' so-to-speak.
For gawds sake don't wax it !
I wouldn't drive it for a while if I was you, I would keep it indoors for at least 2 weeks, just my advice.
(edit) but leave the air get at it and if it's sunny then get it into the sun.
