I was almost gonna buy a can of spray shit for $15 bucks, I googled the product while I was in the store to see if it was any good?
Turns out they're pretty much all shit.
But I stumbled upon a write up of some dude who mixed clear 100% outdoor silicon caulk, with mineral spirits.
Then painted on the mixture & let it dry.
It works. 100% waterproof.
0% Breathable, can't have em both.
I've only done 1 pair of shitty old gloves, but I've got shitty old jackets to try it out on too.
For the price, ya can't beat it.
Buddy started by mixing it in a bucket by hand
Someone wrote in, put it in a 2 liter bottle & shake it.
