Butyrate, lacquer thinner, STC,etc

First off, I'll order the appropriate butyrate thinner from ATS this
morning, so I'll be following the Ceconite process.

Yesterday I found myself out of thinner. Went to the net and got some
indications that lacquer thinner would act as a thinner. I have a frame
holding some Ceconite that's been shrunk, nitrated and silvered. I
diluted some colored Butyrate with lacquer thinner and applied it.
Looks beautiful.I'll apply a second coat later today, just for grins.

Although I know the correct thing to do, I was sorely tempted to use
lacquer thinner.

Does anyone know the process of determining if diluting with lacquer
thinner is better/worse/no different from following the STC?

I've read about the Whittman crash, I believe in A/N hardware; for some
reason however, not being able to do what appears to be an equivalent
process is very irksome. - Mike
