A view of the underside, showing the expanded polystyrene rear frame.
In hindsight, I won't be doing this again! The PVA glue takes 24hrs to set, keeps moving and runs out of the gaps making a right old mess. For how much material I saved and the effort required I think any next buildings will be all plastic sheet. They are quick to build, strong and light.
I then spray painted the building with several light coats of aerosol paint. I didn't want grey again so opted for a sky blue to give some variation.
This was a different brand of paint (very small cans) which had also been in storage for years. I had hoped the small cans would be more precise and better suited to small scale models like this, but despite much shaking I was disappointed with the finish. I'm not sure if the paint has separated inside the can or if the corrugations are just hard for the paint to flow, but even after three light coats the paint is running, pooling and in other areas it isn't covering the plastic at all
I really made an effort to not overpaint, but clearly I haven't done something right.
I'll leave to dry overnight and study it up close tomorrow evening after work. This will also allow the fumes to fully disperse before bringing into the house!
Fingers crossed this hasn't been ruined in the final painting stage
