"Torque-Seal" is just a visual indicator that a fastener or component has remained undisturbed since it was applied. A thin bead is usually laid across the surfaces (such as a nut on the end of a bolt, of the bottom of an oil-filter against the fitting etc) and this facilitates a quick visual inspection.
Haven't tried the acetone yet but that is a pretty decent organic solvent. The toluene did soften it up to the point it would extrude from the nozzle.
