Does anybody know if you can waterproof any old cotton using wax spray or is it just for reproofing wax jackets? Reason I ask is because I was thinking of giving it a go and a 100% cotton dog coat.
technically i'm not sure what to use but i'm sure you can as you can waterproof yurts and they are made out of cotton bek- i know some things but not all of them are helpfull
