Hi,
It wasn't nitromorse but a similar cheapo brand, which is probably the same stuff, and it melted off the slot and prongs on the back of an Elder Wraithguard. Good job I didn't dump the lot of them in there. The rest of the figure also felt soft and bendy.
Also the finecast seemed to have soaked up the paint, so the surface layers of paint stripped off, but the undercoat did not - or well the colour didn't.
Thanks anyway, guess I'll have to break out the primer and hope it doesn't clog up the details, either that or search for your product when I go to the DIY store Sunday, that was the dregs of my paintstripper bottle, and I have some metal figures to strip as well.
