In my last post i mentioned cardboard.... Well it seems to work ok! I hhad expected the card to absord the PVA/water mix forcing me to soak it in over multiple evenings, however it looks like only one more selective dose will be required!

However I did fing it difficult to get the ballast nice and flat, in the end I used a 1" brush and gently laid it on the surface. Don't press or you get a ridge forming around the outside edge of the brush.

Another gotcha is that the drops made slight dest in the surface when drops fall from syringe, so keep it very low above surface.

Meanwhile I've finished off some more buildings, so now the track is starting to look like a layout! Photo's soon. It's gone too dark now...
