Chau B.wrote a review of Nikwax Softshell Proof Spray On on December 30, 2010
I sprayed it on my Burton windstopper fleece and it worked pretty well. The only thing is it takes half the bottle. It says on the bottle that it will DWR 1 to 2 items of clothing depending on how much you spray on.
After it dried, I ran my sleeve under the faucet and it repelled the water. I took a hand full of water and threw it on the fleece, and it beaded. Pretty cool. Recently there was a rain storm and I wore my fleece, the rain drops beaded, but eventually it stopped beading and some drops got through.
I must mention my fleece is not meant to be a waterproof item, I just wanted it to be so I decided to spray it on and use the fleece for light rain conditions, but the recent storm was cats and dogs.
There is a smell from the spray, it's very strong when you first spray it on, but dissipates after it dries. But it is still noticeable. But I guess it really depends on the individual because I don't really mind the smell, it's kinda like Elmer's glue.
