 I tried decapping an MSP430 using both solvents and it didn't do a thing.  I did some research on epoxy chemistry, looks like this probably only works against a very limited number of epoxies.  Its nuclear how common these are.

-When I talked to a sales rep he said that most people use this over Dynaloy Decap these days for IC decapsulation.  The main advantage is that it is supposed to be much nicer to aluminum (ie bond pads).  It doesn't explicitly list IC decapsulation on the datasheet so I didn't consider ordering it.
