RAIN WHEN YOU DON"T WANT IT!!!

I spent a couple of hours sealing an old semi-trailer, it was a warm clear day. The 230 caulk went on very smooth and easy to handle. After a couple of tubes I was getting pretty good at applying it. I finished up and walked inside and was informed that a strong thunderstorm with heavy rain and high winds,has popped up to our west. When it hit we had 1 inch of rain in 45 minutes accompanied with 60 mph wind! Afterwards I went out to look and the caulk looked like whipped cream from a can!!!!! Not too happy with mother nature but, the caulk I had used a couple days earlier held up great! Moral of the story-- don't trust the weather in Minnesota!!
