I used this product on a pair of Lacrosse alpha burly sport rubber/neoprene boots that I had a large tear in them (approx 5in). This product along with aquaseal did the trick. With clear patch you can't even see it and the camoflauge pattern is seen perfectly. Showed the patch to my brother and he couldn't even find it. I had to point it out. Great Product and I would recommend this to anyone looking to patch something up.
