Thanks TXTwilek
I obtain the laquered aluminium here http://www.aticometal.info/ (in person, no online). Maybe you can ask in metalwork companies or metal craftsmen. laquered is "painted" with a lacquer paint style.
Almost everything I used was not online buy.
Yeah! Talon's lekkus are longer than normal twileks.
Pam has said many times in forums that their lekkus are short but, actally, the people that have to tell you if Pam's lekkus are good to Darth Talon approval are "stormtrooperguy" and "Aysel"
(Aysel, am I correct?)
To lengthen, look at the topic of "Acima's Darth Talon 2.0", Acima bought Pam's lekkus and lengthen with vinyl, is a good idea, but Acima never tried to approval for legion501 only did so to enjoy.
Luck!
