Trickiest job on the Beetle build? Painting the chrome trim on the sides and bonnet.
It's thin, and not raised enough to dry-brush.
I agonised a bit about this and then came up with the solution - use a bow-pen.
Loaded with Humbrol silver paint, I managed to place the blades either side of the trim and draw an OK line. OK, but not good enough all the way along.
Dampening a pointy brush with turps, I managed to draw this along the trim and pick up excess paint which was wiped off on a paper towel. Eventually, I did enough "paint lifting" as watercolour painters call the technique.
The results look pretty good so I'll remember this for the future.
