I'm OK with it so what's good for sun protection that will not make it slippery?
303 Aerospace, it will definitely be slick at first on a smooth material glossy material, but it soaks in and doesn't remain slippery forever like some other products do (looking at you Armor All). The stock 3rd gen seat is so textured I never had any issues with using it on the stock seat and hopping immediately.The folks at 303 make several products.
I've used, and shelve the 303 "aerospace protectant". It brings black trim & plastic back to life. When I used it on my Honda seat, it became slick as ice. Soap & water made it better.
Which 303 product are y'all using on seats?
