I used a bottle of turtle wax rubbing compound from Walmart...
Took a couple of applications with a micro fiber towel... but pretty pleased with the results...
Then put a coat of wax on it...
Probably need a better wax/coating afterwards as that part does not last...
But the rubbing compound does it's job. It does take some elbow grease...

 

Took back and still looks bad. $140.00 not happy at all.
