Well, my car is drained, and its not water that condenses as a week or so ago it was -15 and it was weeping then. I really thought it had to do with tire dressing in the past, and quit doing that. It has something to do with the cold as my shop with no one working in it is kept at 45 and there is no weeping on those cars. What ever it is I don't believe its good as I have had to replace hoses maybe every 4 years or so, but daily drivers, no matter how cold, don't seem to do this....and they never get coated-weep. Don't know whats happening.
