Hello, I am after a very cheap DIY spray solution/mix for a very cheap wind-shirt experiment. I want to see how water resistant I can make it without completely ruining its breathability. It is very breathable now.
I have tried "Nik Wax wash in" (have some left over) which adds some WP (but not enough to stop me experimenting) but I thought I might mix up the thinnest solution so I can spray which will add that bit extra WP/WR. Is it turps and silicone? What is the weakest I could try-I want it really thin and happy to re-coat.
At present I can easily walk for some time in light constant rain and it is fine -none or very little water ingress. Pretty excellent really .
But I am thinking why not have a go, so....
It is nylon as far as I can tell and I will take all responsibility for any damage. Given it cost me $18 I am only willing to try a VERY cheap method if one even exists.
So I thought what the hell I have a spare jacket so....
Any ideas?
Thanks!
