Almost every time I've washed my Cruze, I've been applying trim dressing to all the black plastics on the exterior. While I've been binge-watching detailing videos, I've noticed how some pro and enthusiasts would apply a dressing or some form of protection to the grille of a vehicle.
My dumb question is, is there anything I should be doing to protect the glossy black plastic on the grille of my Cruze, or should I leave it alone? I'm not sure if the glossy plastic would be suitable for any kind of dressing.
Thanks in advance.
