I have used carbon fibre like adhesive to cover the black in the same way. The material is very forgiving and it is easy to remove and reseat to get a good result. It doesn't mar the original finish if you decide to take it off. Point to note on this part - it is best to remove the silver side pieces from the surround before starting so you can run the film over the whole base part. Don't just cut to the edges as the heat in the car and direct sunlight will likely see it peel as it gets warm. Leave sufficient overlap in the centre square to fold inside the part and simply slit the side slots down the centre lengthswise and fold the film back against the part so it is held in place once you reinstall the silver side sections. I used a low setting on my heat gun to get the film to conform to the rounded corners under the silver inserts so it adhered better.
