As a follow up - I got a bottle of the Estoril Blue Metallic II touch up paint from DrColorChip to touch up a couple tiny nicks in the paint of my blue Brembos - match is near perfect = can't tell unless you know where to look
Just make sure to shake the hell out of the bottle so it's mixed well. If nick is deeper, apply several coats to bring up to same level as rest, letting paint dry in between
