Interesting questions you bring up. On the Maserati, the sticky coating appears to be for providing a sort of tactile/non-slip type feel, to the hard plastic button underneath. If it was solely to protect the plastic beneath, it fails miserably and quickly (5yrs). Especially on the Jaguar, it’s simply hard plastic underneath, which has fared excellent over the last 18months in Houston weather, likewise in the GTS(6months). If I ever decide to sell, it won’t be over sticky buttons, otherwise I would have gotten rid of our Range Rover or Ferrari a long time ago for more maddening issues. LOL
