I know that most lacquers can be thinned with mineral spirits, but are
you sure that CA glue can?

We do it every day at work. As the glue begins to thicken we reduce it with
a few drops. It doesn't seem to effect the adhesives properties at all.

fyi: Lacquers should be thinned with lacquer thinner, which is a blend of
ketones, alcohol and mineral spirits, depending on what type of thinner it
is. It is the ketones that you want. Dan
