The only downside to this product might be some grout removal tools. They're a bit brittle, but plastic is the way to go when cleaning grout from scratches on surfaces like fiberglass. The real value of this item is the many shapes and sizes of tools for smoothing out new sealant. You get something for every use and they work well. They leave a smooth surface with clean edges. The 90 degree angle is particularly useful for correcting any mistakes you may have made. I've used this in combination with some YouTube tips and am very happy with the results.
