GT - I can assure you that the wrappers are NOT "painted."
I have visited our factories in both Danli (Honduras) and Esteli (Nicaragua) and have been privy to the CAO cigar-making process from A to Z. I can attest to the fact that NO CAO wrapper is "painted."
As far as the MX2 goes, I do know that the wrapper leaves require additional fermentation time - hence, the reason why you are now seeing many retailers 'sold out' - our supply has not caught up with the demand and the production time needed is longer than usual.
Hope that helps....
