Fine line detailing on peco wagon kits

[IkBrunel]

Anyone have a solution to doing fine white detail on peco wagon kits? I use small pain brushes at work all day but I can't get a perfect thin neat lines on the detailing on the Lner brake van kit I did today.

Have you tried masking tape?

The gaps are too small. I thought about masking fluid but thought it might damage the paint.

I've got one of those and they're great but I also have various fine tipped paint pens that do wonders for detailing.
