First he should gain CoC, if he gains it then he should get teached of Adv CoA - I am using those ideas that Cmadvancing CoA teaches the user to flow their haki, so they apply that for the CoC coating.
Long steps for him, but with the RS gone he might gain them in future arc's, not this one tho. He should probably just forcus on Future Sight and be the most evasive fighter rather than learning all those steps, while improving his CoA so he can withstand much higher temperatures of his DJ for use, rather than spam Adv CoC.
