bro dont paint at all , that is an expensive casing nearlly 20g had it been a cm90 then no problem , let it be in the original color .
1 , lets be straight here no one has the master expertise to paiint the casing to perfection ,then is the added stress of it looking good .
if u reall want to then go to a pro-painter , who has all the equipment and can do it perfectly .
it would look cool , chrome is not bad at all , again its ur choise but go to a pro - painter to do the paint .
