I’m about 1/3 of the way through the preparation of the surface of my water in this photo. This shows the river module masked off and after having two coats of spay primer applied. This brings up the divots and gaps in gloious, annoying detail so I’ve appplied a second round of polly filler (the pe mixed type) to the surface. This will be allowed to dry overnight and I’ll come back and sand it all back off in the morning before applying a third coat of primer. This will continue till I’m satisfied that the surface is reasonably flat and dent free.
