Hi all, I am holding off on using my E1 tire dressing until the weather is good again, but I wantt o still have a black look on the tires. My uncle introduced me to the PDMS type dressings, he uses Nu Finish on the tires of his Durango since he lives on a gravel road, he says it dont pick dust up as bad. But, I read on my Nu Finish bottle you arent supposed to use it on rubber. What should I use? And, if its a wax, how should I apply it? Like regular wax, then buff out? Thanks for the help!
