ive used the touch up paint pens from halfords. they have held up fine so far after 2 years of almost daily riding in all weather. the pens come with two tips, a fine one like a pen nib, and brush like nail varnish.
i used the brush to do mine, and the pen nib to tighten up the edges. i also used a tightly folded piece of kitchen towl dipped in white spirit to correct mistakes. i did one application of the whole bike in a couple of hours and rode it the same day.
i couldnt comment on whever it would damage your powder coat or not, but it worked great for me.
