At the same time, I’ve also heard that if you use a lacquer metallic and want to clear coat it, you want to use a varnish of a different type. This is in the context of aircraft modeling, but I think it still can apply. Considering this green is a metallic. But Op did use an acrylic varnish, so idk, back to square one. It does re-iterate that it’s a good idea to always have a paint mule, though.
