The liquid in a can is great for waterproofing outdoors. I have used it on the skylight curbs and gutters on my sunroom. Has not shown any signs of wear or cracking during the past 3 years. Has withstood +40 celsius to minus 37 celsius. The liquid version of this product is better than the spray version.
