Lot of so called protectants give the surface a short-lived shine, while they damage the material on long run
That is well known issue on tire shines.
The only protectant I know that really protects is Formula303. They come in different variates and since I live close to manufacturer, I can find those in local places, but you can order online. Small bottle is not cheap, but goes long way.
