Beacon Stiffen Stuff Fabric Stiffening Spray – Quick, Even Application with No Flaking or Cracking, 8-Ounce

I bought this hoping to use in my grass golf hat. Before, the heat and sweat would make the sides of my shaped hat droop after about 15-20 mins playing. I was leery at first thinking the sweat would wash off the product and again the sides would begin to droop, but they didn’t. It has held its shape very very well. I shaped my hat to where I wanted it, held it in place with a rubber band and sprayed the stiffener all over the area I needed it to hold. I let it cure for 2 days and reapplied just for good measure ( because as I said I was leery ) let it cure for another 2 days and played golf on the 3rd day and the stiffener has done its job. My rim never fell or drooped as I was fearing it might. The sweat never washed it off. My only “complaint” is that the bottle it comes in sort of caves in while your spraying. They really need to use a higher grade bottle for such a great product. Very glad I bought this.
