I washed and waxed all of the cars this weekend, so of course I had to get some rain.
...
It was a very short lasting rain, maybe 15-20 minutes or so, but I'll take it.
It was the most moisture I've seen in several months! Soon after it stopped raining, the sun came out and dried it all up.
Next time, I'll give the Wisconsin method a try and wash and wax the cars wearing the tutu.
