Right, my experience with Humbrol rattle can varnishes is to avoid them. The quality control was horrid, and I had several cans that failed to work from new.
The lower right effect looks a bit like what happens when you apply an acrylic paint over enamel, especially fairly fresh enamel. If I was weathering the wagon I'd be quite pleased with that crazing paint finish! The upper right and left differences could simply be down to humidity levels or differences in how long you shook the can for before spraying.
This is my problem, really. Rattle cans are all fine and good, but I don't trust the contents to spray the same every time.
Now, your mileage may vary, but I have had excellent results using Precision's ready-to-airbrush varnishes. They don't have a tint (the Humbrol stuff is yellowish), gloss is glossy, satin is satin and matt is the best flat matt varnish I've come across. Of course, it supposes you have an airbrush and want to use it! Happily, I find Pheonix-Precision do supply their varnishes in rattle cans. You will pay a premium, but what price quality?
