Model Master paint reaction with Humbrol Gloss varnish

Strange - you'd think that if it was formulated for overcoating acrylics, it wouldn't be a problem putting it over enamel.

I sprayed after about 3 days and a lot of polishing. The can says its "Varnish Gloss 35" but just noticed on the front it does say "for Acrylic Paint and hobby spray" so that may be the answer - it could be just for acrylic, anyway its out the door in anger already

Humbrol in the tins are enamels. If I recall correctly, they made two ranges of bottled clear coats, one enamel based and the other lacquer. I haven't used it, but I believe the Gloss Cote (27307) is a lacquer.

I wonder about the cure.  How long after painting did you apply the varnish?   And exactly what kind of varnish was it?  There are several types of varnish out there.  Or at least clear coats that they call varnish.

Geez I wonder what happened? Both paints are Enamels, one isn't stronger than the other is it? If you were sanding the white I'd assume it was fully cured? I know Humbrol thinners are fairly mild. I'm not an enamel user so I can't help on the cause.
