How to shine up mud gards and plastic?

Armor All.

Had same issue with mine got to the point where Armor All/Back to Black were no longer up to the job.

Bought something that did the job very well and lasts well, can't be arsed to go out to the garage now and get the name/brand details, will post it tomorrow !.

As promised had a look in the garage today, I used, Carplan (a Tetrosyl brand) Black trim wax, bloody messy stuff, but worked really well and lasts well.

Forget anything else. Well worth the cost - '02 Forester still shiny as the day we got it

I just recently gave my 2000 OB the 'Mother's 3-stage wax system. In order to avoid wax drying & discoloring the black vinyl & plastic trim, I used another Mother's product called Back-To-Black. I used it first to prep the plastic & vinyl trim so as to work as a barrier. Worked great. Wax over application came right off. Then gave all my plastic & vinyl trim, mirroes, mud guards, etc. a good coat. Looks real nice. Brought back that 'just off the lot' sheen to the rubber also.
