Did anyboby else notice that the material of the scenery pack is somewhat strange? I drilled holes in mine to magnetise it (to carry it once painted) but the magnets just dropped out of it again. The glue didn't work. I never had any problems with superglue holding different kinds of metal, plastic or resin together, so I was kinda surprised. Anybody else noticed something like this ... and has maybe a solution? Baking Powder? Completely different glue?
