Everybody knows how hard it is to waterproof your Carhartt barn coat. No matter what you do, the motherfucker acts like a sponge, just soaking up the water no matter what kind of miracle spray you apply.
I have found the Holy Grail.
Kiwi (of the shoe polish fame) puts out a clothing dressing and a boot dressing. Buy the BOOT dressing. I found it at Big 5 Sporting goods. You should be able to google Kiwi and find it there. It treats leather and canvas and seeing as your Carhartt is canvas.......
Apply it just like the directions say, but be very thorough. It says to spray a coating, wait 4 hours then reapply. Then wait 24 hours before use.
I hit my Carhartt with about half the can with the first application and about 25% for the last one. I paid special attention to the shoulders and back of the coat seeing as that's where I catch most of the rain.
And be advised that you ain't hunting in that motherfucker for a while and even then you better apply a liberal dose of scent killer. That shit definitely has a smell to it.
It rained steadily all day today and I was in my barn coat the whole time. That shit works.
Okay. Now you make a fashion statement AND stay dry at the same time.
