The direct sunlight makes it hazy and cloudy looking. The way I understood it from the guys that sell it, that is the only draw back. It does't hurt the way it protects your metal. I might add that I have used it on my whole rolling chassis. Which right now, is not exactly rolling. But, it will be soon. It is great stuff to work with.
Hope this helps.
