There is not much to it really.
Take the wood dash out of the car.
Cut the leather to shape, apply a 3M adhesive.
Peel and stick the leather on.
The material is very easy to work with (there is some stretch, and the excess can be tucked or trim easily).
The wood grain is not an issue as the leather is pretty thick.
Push the dash back in.
Took me about an hour.
Easily reversible if you change your mind about the look. (I've already gone through three different versions).
