colour coated strings seem to serve ur purpose well at first, but after a few days of playing some of the colour comes of and those parts are prone to rust, so u hav to start cleaning them, and when u clean them even more of the colour comes out and they collect on ur guitiar like dandruff and soon ur guitar looks liek its decomposing ir sth
what i do now is just use ernie balls anyhow (try the stainless steel they rust slower), and i just clean with GHS fast fret, for a moment of time i even kept my guit in its gig bag when not in use and that helped severely, but i cant b bothered(lazy to zip unzip bla bla) to do so now haha... wait for my next guit with hardcase then easier to put back
or theres always elixirs, just pray the coat doesnt come out
