Hi David,
If you look at the SDS ingredients it appears to be a thin cut of shellac and boiled linseed oil dissolved in alcohol and a number of other nasty solvents.

Hi Clay, that sounds like an automatic disqualifier. thanks for the info.

I don't mind mixing my own shellac was just looking at an easier way

That's been around forever. I think it was even suggested for use in Sloane's books. Something like Royal-Lac would be better considered a 'modern' French Polish imho.

I used Qualasole once back in the 70's and was totally unimpressed. Didn't know about the toxicity issues at the time, but it just never got a build like good old shellac.

This stuff is functionally awesome for its intended purpose, which is touch up work. It builds very fast, dries hard very fast, has a nice amber color which matches most aged finishes, doesn't require any additional oil, and will burn in to anything that is burn-in-able. I use it for spot repairs all the time. I do not use it for finishing and cannot recommend it for that purpose. The main drawback it has is described well by Clay: It is viciously toxic. Wouldn't surprise me if just reading the MSDS could give you cancer! I'd like to stick around for a few more years, and the amount of exposure that would be required to finish an entire instrument with it is well above my personal safety threshold.
