Not the same thing! Epoxy resin and polyester resin are two
different chemistries.

 We have medium voltage motors impregnated with polyester
resin and when the windings go bad we machine (cut) them out.
No "practical" solvent was found to remove the polyester,
although methylene chloride (TOXIC!) did attack it.
