Reddit mentions of Solution Finish Black Plastic & Vinyl Plastic Trim Restorer - Car and Truck Polish - 1 oz.

In another thread that I can't seem to find someone recommended this stuff:
https://www.amazon.com/Solution-Finish-Black-Plastic-Restorer/dp/B006NZQ3T8

I had it bookmarked for myself on Amazon. I have never used it, never tried it, and know nothing about it except that someone in another thread recommended it highly for scuffs on the glovebox.

Edit: still can't find the thread. I'm giving up. Reddit's search system is terrible. Anyway, there was one more thing that I remembered from the post and that is the person who recommended it said that it changes the color of the glovebox slightly darker, so you don't just apply it to the scuff, you apply it there and then over the rest of the whole thing. And when it's done it will be a bit darker but it will look like new and still match the rest of the interior. If you try it, let me know how it goes.

This one, right?

How do you apply it? And is it something you need to reapply every few months, or more of a permanent/semi-permanent solution?

Thanks for the advice.

Sweet!
That's really nice looking and I don't want to offend but I noticed the bumper ends and maybe the hood latches aren't as black as they probably used to be.

Try this stuff for things that just won't turn black with normal cleaners and protectors.
I used some on my Polaris stuff that had almost turned white and it really works.
Works on fingers too so you gotta wear gloves.

They say this is the stuff to use. Never personally used it, but heard nothing but good things about it. Also a heat gun will restore the faded trim/rubber, then go over it with solution finish and you'll be in top shape.

For black use this product and just follow the instructions. Solution Finish Black Plastic & Vinyl Plastic Trim Restorer. Determine which size to order based on the amount you need to restore.

For white use this: Salon Care 40 Volume. Brush it on and then leave it in the sun for 8 hours, if possible. Direct sunlight, not through a window. You need the UV rays from the sun to react with the cleaner for the desired effect. If you have a UV light hanging around you could use that too but most people don’t so the sun will be your most common UV source. You can repeat the process if necessary but if the day you clean is sunny enough you shouldn’t need to.

Both bottles should last you a while. Obviously start with clean electronics so the restoring process isn’t fighting through dirt or grime but it sounds like you’ve already done that. Good luck!

This is the one I got and still have 3/4 left after 2 times use. Dont buy the big bottle because you only use it as little as you can. There a lot of youtube video out there. And it safe for paint to so dont have to tape everything.
