Thanks TBM,
Never tried any plastic trim finishers, will give it a try, Thanks
Autoglyms Bumper Care is superb on black or grey plastic
Haven’t used it for a long time as I don’t have any unlaquered black plastic bits on either of my cars but I remember the first time I used it on a black bumper years ago when I was first recommended it, I thought it was magic
It’s a thick silicone gel but seems to make plastic look new
