Having got excited with the application of polish and getting it on the hard plastic parts of the car ,I wonder if anyone has found a way of removing it.
I've done that a few times. I usually use forever black dye to restain the plastic black again.
Gtechnic do a bumper restoration/protection product (C4 permanent trim restorer) that I think works really well. Bit of a faff cleaning the plastic parts with alcohol first, but comes up great and stays good for ages
