Should add some waterproofing. There's 2 parts to it, Nikwax Tech wash first, make sure you clean the washing machine soap drawer out thoroughly first and give the washing machine a rinse cycle empty. Wash item in tech wash. Then wash again with Nikwax Tx direct for the waterproofing. I use them regularly with my hiking jackets and trousers, it's great stuff.I’ve got an old ex army smock that I use, it isn’t waterproof but I’d like to make it showerproof. Do any of the wash In treatments work?
I’m not expecting them to turn water in a prolonged downpour just something to turn the odd shower.
Thanks

Aren’t nikwax anti hunting?
I think its dependent on the material as to the treatment to use, I use nikwax on tighter fibres and graingers on more coarse materialTried the Nikwax stuff a couple of times. Can't say it worked.
