Depending on the look you like i would say in spring weather you could get 1.5 months out of it with a matt look. 3 weeks if you want a little glossier. Not that much harder to apply to tires and i did a decent cleaning job. Im looking for 2 months plus.
In th i dont want it thread Guz is giving his away. Take him up in it and give it a try
I had no issues with browning and didnt do such a great job of cleaning. I have nitto tires and i’m starting to think tire compounds make a difference in browning
