I guess I'm next to be targeted, as I've got way too many unfinished projects.
Actually, I need to do something like this, as I’ve got an old freight house that I’ve been meaning to extend. And I’ve got another old kit that needs to be redone as well. Oh, the shame of it all.
I’m going to try the Weld-On 16 on this stuff. What are you using for adhesive?
You’ve inspired me to be a lot neater in my work. I’m not quite there yet, as I still let too much stuff gather, but it sure is nice to have a clean workbench!
Bruce,
Not to worry, MM is plenty busy checking what I’m doing. Latest coup is checking for correct spelling, well I’ve given up long ago on checking for that. But if that’s his pleasure: “Even a blind chicken will find a kernel sometime.”
I just ignore him, but he figures that even comments that aren’t addressed to him should concern him. Hey, if that’s what it takes, who am I to say? But it sure looks like they spell “auxiliary”, a bit different across the pond.

The solvent I use is M-E-K, works really well on that material.
I’m doing the random stone foundation using the dense pink styrofoam, cut the pieces to size and glue them together, then use a bit of diluted M-E-K to give the styrofoam a bit of texture, carve the stones with a hot awl, give it a base coat of primer grey, cover with a thin layer of drywall compound and paint with acrylics. That way if the drywall chips it’s at least not pink underneath.

In the smaller scales I use the white, crumbly styrofoam. No need for M-E-K, the heat from the awl does the trick.
BTW is Weld-On 16 an adhesive or a solvent?
