Hi @raesumthin , welcome to the community! I hope we can help with this issue. I have a feeling you (and I, since I have the same issue with pearly acrylic from Houston Acrylics) will just have to go to another manufacturer. In the meantime, see if you can salvage the stuff by only using it for applications where the edges will be hidden.
I’ve tried alcohol, ammonia, Goof Off!, and plain old abrasion. None of them are satisfactory.
