Looks fine but i haven't used it yet as I bought it to reproof the trousers it arrived with. I'm hoping i won't need to do that for a while.
I bought this waterproof a cotton coat not from WAWWA, I wanted to try and see if it worked as I needed to re-waterproof my rain hat. It worked pretty well and my coat is now waterproof, the water sits on the surface and runs off, before it would be absorbed into the fabric.
Not too expensive, so it’s worth giving a try!
