Removal of potting compound

Has anyone ever had success removing the hard glossy type of compound used to seal
various kinds of electronics ou there in the trade?

I am trying to get at the bobbin and diodes inside a small HV (FBT) transformer
to study the material used in construction.

I have heard there is a solution it can be soaked in that dissolves only the potting, and
leaves other material undamaged, but I dont know if its merely acetone or something else.

I tried baking in the oven a while, and it didnt seem to make the epoxied area weaker and when I tried pulling
on the pins, the pins came out.

If you have the means, the coating can be removed by sandblasting

These 2k resin cast parts cannot be repaired. They do not have a solvent that can be professionally used to prevent damage to the internal fittings. Unfortunately, new, cheap technologies have brought this with them.
