I know, been caught out many times! Car will look like a right mess, reminded me of a girl crying and her eyelash product has started to run down her face lol
Dont worry though
Try washing it if you want, use plenty of shampoo, you might need to make a few washes though. You might get a smeary finish, but the next time you wax her it'll will remove this, and by the looks of it the weather will help you there!
Health and safety notice lol : Make sure you wearing a warm coat, I washed my ST in the rain yesterday becuse of Rain-x started to run after it started to rain(same kinda position as you really). Now have a cold developing
Managed to get most of the resin off through lots of buffing, very greasy as someone said, then shampooed with the autoglym with double concentrated mixture, looks as though its all come off but until better light i wont be able to tell. So glad id only managed to do half the car by the time it got wet!
