| In the past, I used Autoglym bumper care on the trim around the roof (guttering), but now it has turned a sort of light grey/white colour! As this particular trim has a rougher texture than the wheel arch trim, what do you guys use to keep it looking like new?
Autoglym bumper care is good on the rest of the black plastic trim (wheel arches etc), but it gets streaked in the rain. For this reason, I use turtlewax back in a flash - I think this won an Autoexpress product award for the best trim cleaner... |
