I’ve got a can of SC1 just waiting to use on my machine. Most of the threads I can find on this have mixed information.

Dulls plastics.
Makes em look great.
All in the same threads.

Hoping for some more recent information on this!

Specifically for me, wondering how the 15′ Limited matte painted plastics react to it. I’ll try it on an inconspicuous spot soon if nobody has tried themselves.

If everyone lists the machine they’ve used it on and the colors of the plastics I’ll update the OP so others can find the information quickly!
