Had the same issues. I had to do mine twice before I figured out how to get the stuff to stick to the various contours of the center console - especially the clock area.
Spray the part to be covered with adhesive
Wait 1 minute
Spray again around clock and vents (needs extra hold

)
Spray the back of the Neffy Wrap
Wait 1 minute
Drape the Neffy wrap and press into clock and vent recesses
Flip over
Spay adhesive on the areas around back where the neffy wrap will fold over
Fit vent and clock openings
Finish the rest normally
One more install tip, when you are cutting the openings make lots of small cuts. Instead of just making an 'X' an folding it in;
cut the edges so that you have lots of little strips.
This way you get a better fit and much more ability to adjust the fit.
See example below

Lastly, if you don't like it just peel it off and remove any left over adhesive with Goof-off and your console will look just like it did before
