I thought it was ABS so I stayed away from the acetone. Maybe it is a blend/ mixture. I also notice that in some 3D filament which are supposed to be 100% ABS or PLA.
Anyway, I was able to fix it.
Normally I would have done it with water but I used Vallejo earth texture and needed something stronger to remove it.
It is cool stuff for mimicing desert dioramas, but didnt gave the effect on the lid I was hoping for.
