Another vote for 303 Aerospace Protectant. I too hate a shiny dash and the 303 isn't very shiny and has great UV protection. It doesn't look the same as a completely unprotected dash, but I wouldn't call it shiny, it just looks "nourished". Just follow the instructions and spray it on (I usually wipe it on with a fairly drenched microfiber cloth to avoid overspraying inside the car) then buff it off *very thoroughly* with a dry microfiber towel. You can use it on our leather as well since it is vinyl-impregnated.
