Firstly I can't believe how good this spray is, I've used this Scotch Guard spray on two pairs of expensive shoes so far, & I sprayed them outside on the doorstep, because the fumes were a little too much to spray them inside. Spraying the shoes wasn't a problem because the spray covered very well & evenly. I left the shoes to dry for 12 hours as it told me on the can &. I then wore a pair of them. The result was excellent as later in the day it started raining & I had to go out, the raindrops were non exsistant on my shoes & I came back with a totally dry pair of shoes, I couldn't believe it. Also when I got home I also had a surprise, my doorstep was covered in little droplets of water, just sitting there. Now when it rains my doorstep looks dry but with little droplets of water forming on the top of it. I've treated more of my shoes after trying it out, & I've had the same results, so thumbs up to the Scotch Guard & I will certainly keep on using it in the future, especially with all the rain & damp weather we get in this country.
