How to restore exterior black plastic trim

[Mike Phillips]

Great tip!
Never thought about using the carpet brush for plastic work.

Takes all the elbow grease out of the job and actually works pretty well. For places you cannot use a brush then you want to use elbow grease, a good APC type cleaner and some type of application material that has a nap, either microfiber or terry cloth and you use the nap of the cloth as a form of mild, non-scratching abrasive.


My Power Point Presentation for my class this Thursday at Mobil Tech Expo goes into more detail.

Great tips. Thanks for the review Mike.

Hey Mike, Don't suppose you could throw some Collinite 845 on a few of those trim pieces and tell me what it does to it, eh?

My guess is most traditional waxes will eventually dry enough to leave a white stain.


Kind of goes against the grain to put a wax on rubber, plastic and vinyl trim...

Kinda what I had thought, though some members here have reported otherwise...

This may be a bit off topic.

I've been using Meguiar's Ultimate Wax (LIQUID!) to maintain the plastic on my truck (that monster has more plastic parts than a Revell model). It works well if not just plain good.

How this will work on plastic that has 'gone around the bend', no idea.

Just my $.02...

I found spray wax after treatingthe plastic works well. so buff on sometrim product then wait an hour and spray on then buff off some spray wax. left no white residue and improved trim restorer or trim conditioner durability. 845 will leave white residue if accidently left on trim. I should know... I have to remove some in the spring.

I use 845 on most of my black plastics. The key is to work it in well and not let it dry with any appreciable amount of product on the surface. Rub it with a dry MF until it seems like ther's nothing left. I did my DD Olds, which sits outside 24/7, in mid November. The plastics still look as good and bead as well as the paint, which got 2 passes with 476.

If 845 worked on tires, I could avoid exterior dressings completely.

I'm surprised no one has mentioned Black Wow trim restorer. I purchased some a few months ago and really like it.

I believe it would protect the plastic that is oxidized, but not restore them. I believe you could put on a black trim revival product, let it cure, and then put on the wax on top. I'm not sure how it would bond, but in theory it could provide protection for the black trim revival product.
