Just got this back from iCarbon customer service..
Hey Jeff!
The Matte Carbon is clear-coated just like glossy carbon, with the only exception being that the clear-coat does not reflect.
Just like Matte paint, you cannot wax Matte carbon, just regular soap and water is perfect. You can use some quick detail from time to time, but soap and water is perfect 
That pretty much covers it – let me know if you have any other questions!
Best Regards,
The Sales Team
