Visitor Armor -- How should I upgrade it?

So, I'm doing the Visitor Event Quests in JapanMS. I'm guessing we're on Stage 2, considering this is week #2 of its implementation (I have no clue, honestly). I just completed the part where you had to sneak past the aliens and do that weird ass mini-jump quest thing for a crystal or whatever. I got my Bing Armor and I currently have 881 medals from talking to the researchers in the one lab.

How should I go about buying/using the cores on the armor to get the STR armor? And I also need about 11 extra DEX to wear my knuckle with that. What should I do?

Also, how do I make it permanent? I heard I need a specific item, but how do I obtain that item?

Hmm lets see.
Upgrading armour: You need to scroll it with the cells evenly to begin with (until they all are 12+ if I remeber it correctly). 1 cell on each piece before you put a second on any of them. Scroll the suit with DEX first if you do not care about the look. The suit will take on the appearance of the atribute that it has the most of, it ill become a visitor piece when it is 10+ since you are lvl 120+. You need a full visitor suit (meaning 10+ on all equips) to be able to enter the level 60 and 120 PQs.

Making it permanent: During stage 4 there will be means to get crystanol molecules from repeatable quests. You will get less than 10 per quest chain but you can repeat it instantly. You will need 1000 molecules to make 1 piece permanent. Clearly not worth it in any way. You cannot potential them, and even if you could, they would get poor stats because they are level 0.
