It is those damn details that get you.... :-) Gamma Butyrolactone is a bit challenging to get hold of since it was found to be the "Date Rape Drug".... Details details.

Nitromethane is also an excellent solvent. Methylene chloride is the most effective solvent, but is toxic. Gamma-butyrolactone is also effective at removing cured cyanoacrylate, and has low toxicity."

Loctite sells a solvent called 768 X-NMS Solvent that works pretty well, but it is expensive. Anywhere from $20.00 to $37.00 for a little 1.75 ounce bottle depending on where you buy it. I do know that it is composed mainly of nitromethane with a little bit of toluene according to the MSDS. My question is; I can get a gallon of nitromethane at a high-performance auto parts store store nearby for $50.00 a gallon, would pure nitromethane do the job? Or do I need to add the toluene as well? The MSDS gives a range of percentages of both components, but is kind of vague: http://www.rshughes.com/images/products/docs/zwNFyUtpQskOxsrawO1uew.pdf I'm just trying to save a little money is all...
