Need to dissolve epoxy potting in ignition coil.

[NiHaoMike]

Sonata, 2011 model year onwards. Its 35 MPG highway rating was, at the time, considered really good for a midsize car without hybrid technology.

I have a General Motors LSx ignition coil (has a potted coil driver cct inside) and I need to find out the just exactly what this circuit inside is. I have looked into what is involved in dissolving the epoxy but the chemicals needed  sound hazardous. Can anyone tell me of a company that could do this for me? Preferably Australia but United States is also okay; have a contact over there.

P.S. Don't anybody say just use a MC3334. They are not suitable.
I have been building ignitions for 37 years.

Most epoxies that I am familiar with have a "glass transition temperature"... if you heat them up enough the epoxy can be peeled away with a dental pick.  It's not particularly pleasant work and a fume hood and organic vapor filters are needed. Most chemical's that dissolve the potting compound would also attack and destroy any  circuit boards as they are also epoxy based.
