yeah its still glossy because its relatively fresh. Silver would look good I think! I would advise going smaller than 2-4mm (Marker size, that's what I used) if you're going for something other than black as it's quite easy to mess up which you luckily don't really notice with black
Doesn't look too bad, think I might give it a go on my Pre Cursa. Looks like a gloss effect?
edit: Just re-read, it'll dull over time. Maybe silver would look alright...
