In a large bucket, mix one cup of soybean oil with four ounces of turpentine. Next, grab a sturdy brush to apply the solution to your cleaned and prepped garment. Tip: (Put down newspaper before you begin). Soy and turpentine are stinky and require a large open area for your safety. The fumes are flammable and can be quite dangerous.
That said, this method works well, and especially so on dark item as this method darkens the fabric. Let it dry completely over night and outside. The smell will be palpable for a few days but it will make clothes waterproof.
There a few “perfect” waterproofing options. There are pro’s and con’s to each method. We suggest you try a few for yourself on extra rags or small areas of your clothing that you wont notice later.

The turpentine soybean oil mix looks a bit sketchy, are there any other oils that can be used? Mabe oils that don’t have a soy odor and grit to them?
Try castor oil mixed with beeswax.
I am just going to buy a wax bar, it’s easier and less risky than these homebrew methods.
