I use Vinylx protectant, no raw silicone oil which can damage a dash after a while.
(409 or Windex-bad idea-also any chems that may off gas or are too harsh).
Its buffed in after application, and this one is the low shine/mat finish.
...not antistatic - look for antistatic especially if your car is black.
..but after all that elbow grease it has a dark low shine & looks new inside, but no greasy or oily residue, provided you buff it good and let it sit for a while in normal temps - like 40* and up,
and maybe buff again if you notice any residue. But I havent had to do that.
(dont apply in direct hot sunlight or when its below freezing.)
Use it on any hard textured black surface and plastic on outside and inside;on the doors, dash, console, center stack, door seals, all other seals(especially windshield & sunroof), liftgate, 3rd row, rockers, bumpers, valiance, etc, leaves everything nice and new looking & UV protected until the next application - for external-approx after every car wash or at least every season.
I did the dash too.
There is some reflection but not any more noticeable after a few days, I lightly laid it on and buffed it out well.
I think it would be a problem while driving if you put on too much for sure.
You need to buff it in good, applying it then leaving it is a disaster.
Do not use these type of items on the inside on the pillars or cloth-like sections around the dash, pillars, cargo area, and doors. It cant be buffed in as the texture is too deep and tends to pool in shiny areas on these surfaces. Stick to any hard plastic.
DO NOT put on the door step areas and hand grabs.
Regardless that it says not shiny or slick, all these products will be slick until enough use, feet, etc dull it again. Its slick right after applying. Use non acidic soap and water for these areas. (baby soap is usually PH balanced.)
