Hello, 2 weeks ago I primed, spat, primed, then applied base varnish and clear varnish in several layers, always let it dry in between. Now I wanted to polish, but the polishing worked in the varnish and the varnish becomes dull. Then I wanted to pick up the polishing with spirit (not nitro thinning), then the clear varnish peels. How can the lax spirit dissolve the clear varnish after 2 weeks, what happened there? MfG C hris
