I'm still working on the two tone paint and I've tried some of the tips shown in the following pics.

First tip, I applied the tape and with the end of a paint brush pressed it down between the battens. second I applied a coat of the vintage white over the edge of the tape.

Next I applied the Green.

This shows tape removed and creep greatly reduced.

And a side project I've been working on. The train order boards.

Next: I have to more sides to paint on the engine house and we'll move on to assembly.
