Morning all. I currently use 303 which is pricey, disappointing and my God once you read the warnings on the back you'll only use when wearing a hasmat suit!
The other product I like but doesn't last very long is AG bumper and trim care

What are other people using at the moment?

 

Some of the ceramic coatings work brilliantly on plastic trim. SiRamik SC15 works superbly, and can also be used on paintwork, wheels and trim.
