Howdy I've just applied a mix of Humbrol 85 and Humbrol 147 to the underside of a model. They are both matt, but it has dried to a high gloss finish. From looking around, it seems I mightn't have stirred well enough, although I thought I had. I stirred them both individually before mixing, and obviously again while thinning and mixing. It's getting a bit hot where I am, maybe that was a factor. Humbrol gives the following explanation: 'When Humbrol Matt or Satin paint dries glossy this is due to the matting agent not mixing properly with the paint, usually caused by the paint not being stirred thoroughly or regularly enough. However, this can easily be rectified by applying a coat of gloss varnish, which will dissolve the matting agent.' I'm a bit confused about what this means in practice. How does a coat of gloss varnish dissolve the matting agent, when the paint has dried? What I'm basically wondering is, what effect will gloss varnish have on matt pain that has dried to a gloss finish.
