Krack

it came with the furnace as a kit. I think it looks fine, felt fine, mixed, applied, and set well. it's definitely slightly dusty.

I have wool coated with rigidizer. I wanted to coat that with layers of satanite, but I am finding that this is very not ideal because the rigidizer has a somewhat dusty surface and doesn't allow the satanite to stick well. If it does stick, the satanite sometimes pulls and detaches the rigidizer from the wool. Sometimes applying pressure cracks the rigidizer layers. So... Is this similar to other people's experience when putting satanite onto rigidizer???
