Re: how long should a waxing last
Welcome to the neighborhood!
I think we've had almost as much rain in Jacksonville as y'all have had in Mouse Town and both of my cars are still beading just fine. I have noticed that if I get a layer of road film on the car, then the water doesn't bead as well. I guess it's because the water is on the crud instead of the wax. At least the wax is still protecting the paint from the crud.
My GTO was last waxed with Mothers PowerWax back around Christmas (and was going to be done this past weekend until the rains came) and still beads just fine. Including right now (5/26 at 8:30pm) because I got caught in the rain on the way home from work.
I think you'll find that your beading will come right back after your next washing.
