I use it on every square inch of my boat, inside and out, and on the tires, dash, and leatherish seats in the MoHo.
The wet-suit seat covers in my old jeep came with a bottle of it to spray on the seats to protect them.
It does a good job of protecting the stuff from the desert sun, dries to a nice shine, and isn't sticky after it dries.
