Neville that sounds like lacquer by the description and considering that lingo changes from one country to the next, it is quite possible that what they are calling varnish, we market as lacquer at least here in the US. Lacquer thinner is nothing more than acetone or acetate or similar liquid. It will also strip old varnish and of course that is what women use for nail polish remover. Varnish thinners wont strip strip varnish so chemicals like naptha, toluene, minerla spirits and the such are only good for thinning the product and cleaning up immediately after application. Once the curing process has begun they have no effect on actually thinning the varnish.
