i agree with cletis, that is if you remember to put it on before it starts raining. i took the ashton to stovebolt headquarters at the beginning of august. on the way home i was going to be following the storm which was going to be 200 miles. just before it was getting ready to pour buckets i was lucky to find a car wash to pull into and applied the rain x. it was raining so hard i would have pulled over with electrics in a modern truck. i waited it out and when it slowed i took to the road. the problem with the ashton is that they swipe too fast. so i am constanly flipping them on and off. my 40 i can control the speed and they're cool to watch. as said before you have to time them when pulling a good hill.
