Exactly; Do Not wrap them!
Yes they do come with a ceramic coating. An "upgraded" version compared to the older white looking ones.
The new coating looks like a cross between jet hot & silver powder coating.
I too gave mine a few extra coats of 1200 degree high temp paint with ceramic for good measure.
Do not skip the curing instructions either...
