I used a Scalecast mould set for the engine sheds I built last year - very good product once you get the hang of using them. They tend to use plaster for the casts although, as you know, I preferred to use resin. Plaster may be a bit trickier to paint, maybe?bulleidboy wrote: ↑Mon Sep 05, 2022 11:11 pm Steve - it was the Scalecast site I was looking at. They do look promising - serious food for thought.
Should you decide to proceed, and go with resin, let me know and I will happily give you a few tips and a relatively inexpensive supplier of materials.
I think their wall kit is about £30 with 2kg resin a similar price - quantities depend on the depth of the mould but you can add inert fillers to the resin mix to pad them out a little and stretch the resin a little further.
Also, once you're finished with the moulds, you can always sell them on eBay to recoup the initial outlay.
