I just bought a new to me 2014 King Quad 500axi in black. It was scratched up pretty good so I decided I wanted to try wet sanding the plastics.

I used the plastic on the front of the handlebars as my test spot. I started with 320 grit and progressively went to 400, 600, 800, 1000. I followed the instructions of a guy on YouTube who restored a plastic Honda dirtbike tank with amazing results.

What I was left with was smooth, scratch free plastic...but it is now matte black!

I even tried buffing it out with Meguiars Ultimate Compound and there is still no shine. It also now seems to show temporary marks when anything touches it. If I wipe it with a clean cloth, you can see the marks in the direction that I wiped.

It almost seems that the the plastics were sealed from the factory and when that is removed there is no way to make them shine again. I've even tried wd40, polish, tire shine to give it some improvement, but nothing helps.

Has anyone else experienced this and have advise that could help me out?

It ain't black, but this looks like it brought the shine back a bit:

Saw another video of a guy using a torch after cleaning, up to you if you want to try that though.

then I saw this comment:
Looks good but only way to truly fix it is to wet sand the oxidation off starting at 320,400,1200,5000 then plastic polish. Still looks good though 😊

This one seems pretty good too.

Sand with block, buff with wheel and light pressure at an angle. Turns out pretty good

Thanks for the response. There is no oxidation on the plastics, there was just a lot of scratches. Once it's sanded to 1000 grit it almost feels like "soft touch" plastic. I don't want to use a flame. I was going to try a buffing wheel tomorrow hopefully. I'll upload some pictures to better show what I'm talking about.
