Restore plastic Jeep fenders

[bigirn]

I bought a used Jeep that has the black/gray plastic fenders. They are now dingy gray with old wax and grime embedded in the pebbled surface. I tried regular car wash and brush but it didn't do much.

I'd like to get them back to black with no streaking from the old wax over runs. Don't want glossy.

Does anyone have a protocol? Also, trying to search this I saw IPA. Pardon my ignorance but what is that?

I really appreciate the help!

IPA is isopropyl alcohol.

I would scrub them with an all purpose cleaner (apc), then use a product like Blackfire Total Trim & Tire Sealant. In my experience it darkens and protects very well.

Or Turtle Wax has a trim coating kit you can try, I have no experience with it but people like the tire kit.

Hello. IPA is rubbing alcohol.... comes in various dilutions... 50%, 70%, etc. Ammonia also cleans plastic fairly well... is often recommended before painting. I've used Forever Black as well as KIWI leather dye to restore plastic.... Forever Black will last longer in my experience, but the dye isn't bad in that I've gotten 6 months out it.

Use Solution Finish Plastic & Trim Cleaner and seal with Solution Finish Black Trim Restorer.

An APC will work as well. You can use the Turtle Wax Trim coating which works well. I have found it works best on textured plastic. Meguiar's also has a new ultimate black trim restorer that claims to last 100+ washes. I am currently using it and it seems to be doing very well and looks great.

To clean the frayed out fenders I would use a medium scrub brush and all purpose cleaner. This is going to take a lot of time to complete. It,is not going to come off easily. The products like back to black is only topical. The cleaner does work but you will have much better success using APC full strength. When done seal the fenders
