## Description

N/A

Review: Adds repellency to work pants. - Used this to proof my jobman poly cotton blend work pants. My work pants are 100% not waterproof initially. Soaks up water like sand. I washed my pants per manufacturers instructions, then used the hand wash method with cotton proof. Bucket of hand hot water and 50ml of cotton proof. Soaked for 5 min, then mix to flip pants over, and soaked for an additional 5 min. Ran it in the dryer on the delicate cycle and then let it hang dry overnight. Made my pants water repellent. Do take note that this does not make my pants waterproof. I have rain pants for when I have to be outdoors in the rain. But this will help with brief showers, accidental water splashes and short walks between job sites. The coating also helps repel dust and stains so I can wash my work pants less often. Cotton proof liquid was thicker compared to their soft shell proof. So I had to mix it with a butter knife and shake well before pouring.
Review: If water pools for 24 hours, it gets past this product - I want to give a 5-star but the waterproofing of the entire surface is hard to achieve, even though I know I have bought the right amount. I can say that for the areas that this product did get onto, it definitely works. One note : It does not work if the water pools for 24 hours.

### ⭐⭐⭐⭐⭐ Adds repellency to work pants.
*by C***. on October 4, 2020*

I want to give a 5-star but the waterproofing of the entire surface is hard to achieve, even though I know I have bought the right amount. I can say that for the areas that this product did get onto, it definitely works. One note : It does not work if the water pools for 24 hours.

### ⭐⭐⭐⭐⭐ Worked for vintage M65 Field Jacket
*by A***R on December 7, 2023*

I was a little nervous given the variability on some of the reviews but I washed my M65 field jacket with tech wash and then cotton proof in my washing machine and I have to say that I'm pretty impressed, water beads up on rolls off similar to what the other field jacket user reported. Short of waxing, cotton will never be truly waterproof but I would say that if there were light rain or showers in the forecast I wouldn't be concerned. In the bottle the proofer smells a little like Elmer's glue with a trace of vinegar but I can't detect it at all on the dried garment.
