Default Doeas this matt cote look good?

I bought this Humbrol 49, "Matt Cote" to be applyied as a final layer on a tank. But before ruining the model, I want to show how this product looks and the results after a test.

I stirred the product for quite a long time.

Even being matt, it should be clear, to some extent. In the past I'd been using Hombrol matt cote from a bigger glass container (28ml); but this time I could only find this one as available.

I tested it on a plastic track that was painted brown, now look how it ended after one layer of this varnish.

Do you think it's ok, can I use it or should I go to the shopand claim for a replacement?

Thanks

Looking at the photo of the tracks, it is hard to say whether the product has gone bad or not.

In your photo, there is white overspray on the red bricks.
Is that from the matte finish?
If it is, then that does seem wrong.

I have not used the Humbrol brand before.

What I do know is that in general, a matte finish is also going to dull the color some.
Most matte finishes are a bit 'milky' in color and slightly opaque until they dry.

That white overspray doesn' exist, it's just a reflection of the camera flash.

I agree in that matt finishes are a bit milky but I've built 5 rc tanks before and never saw one with it's paint completely altered by the varnish.

I'm afraid I was wrong: that white overspray seems to be from the matte finish. Maybe it wasn't properly thinned?

Another question.
What medium are the layers of paint and varnish?
For example, are you spraying an enamel over acrylic?
If both the paint coat and varnish coat are solvent based, then the 2nd could potentially 'dissolve' or affect the previous coat.

The paint is enamel and I'm using the same thinner agent. Never had the problem of dissolving a paint.
