The big update:
What a prompt and pleasant reply from ProVape...

------------------------
Hi Reginald,
Oh dear. I am very sorry to hear this is happening so soon. The colored finish is a durable cerakote that will succumb to daily use within time, although it should not be showing excessive signs of wear so soon. If it is stored in your pocket or near anything metal like coins, this will definitely speed up the process of normal wear and tear. I might suggest a carry case or caddy to extend the life of the paint. The good news is though, I would be happy to exchange your tube for you as I do not believe it should be fading so quickly. Below are the return instructions.
Please fill out the attached form and include it with your return. RMA’s that do not include the form will be returned to the customer at their expense.
Return address:
blablabla....
-------------------------
There is still places where customer service has meaning in this world...

Looks like from the answer, and comments in here, that mine is one of those flukes...
so I will be returning it tomorrow and hope the mail systems/customs will be as efficient as ProVape customer service ... hehehe
Thank you all for your input and support, I'll be sure to report back in a month or so, when I have the new one under scrutiny.. ;-)
Cheers all
