I am drawing a PCB layout with a Dalo pen at the moment. I have two pens that I've had for years and they still work!

There are a couple of large areas of copper that I want to leave and I know from experience that trying to block out a large area with a Dalo pen is not easy! Uses a lot of ink too.

I read on another thread on here that someone had used nail varnish as an etch resist so before I go off to the Pound shop to get some, has anyone else tried this?
