Lol, I'm guilty too. I tried black magic protectant on my new black shoes. It lasted maybe a day or two. Next, I'm tempted to try M40 vinyl/rubber spray, any takers on that? Also, this is just the beginning of using car care products in house for me. I've polished all the metal fixtures in the bathrooms and sealed everything to prevent water spotting lol. It's definitely a funny feeling when you shut the water off and see your sink and drain sheeting off water!
