KEE for some reason don't sell parts to individuals in the UK so you gotta go through a third party if your guns out of warranty. BZ or fatbobs in the UK be able to get you them though.
Bet it aint cheap though =/ Id just grab some thinners wont take long doubt it would touch the anno underneath what you got to lose.
Cheers for the advice! Luckily, Foot had a marker in the colour I needed and we managed to swap out parts before his went off to be annodised. Gloss lime green body with dust black fitting look amazing
