Hey everyone. I just picked up some oem window visors for my em1 and I was looking to fix em up before I install. They're in decent condition overall, they're pretty faded though. What's the best way to fix these up to make them look new?

 

bump here's a pic of the wear. the sun cracks are only noticeable in the light.

 

An old man told me they used to hit aircraft canopies with a heat gun to clear them a little in WWII...
Probly wouldn't take much to ruin it tho.
plastic polish?
make them look new?.....nothing
