Mr.Topcoat problem

[Guppy]

I just finished airbrushing a couple of kits and bought some Gunze Sangyo Mr.Topcoat spraypaint to clearcoat the kits.

In the past I've used Mr.clearcoat and Tamiya clear coat spraypaints and they've worked fine. This time, everything went a pearly opaque colour - you can really see the varnish. I assume I used too much as I don't imagine these paints would have an expiry date and go bad.

Question.. is there any way to remove the varnish without having to repaint? It would pretty much mean starting again which makes me want to cry.

PS.. Mr.Topcoat IS acrylic isn't it???

PPS - I did a test spray spraying lightly on a few pieces I was gonna throw away, and I got the same 'pearly' effect. Second question.. Can clearcoat in a spraycan go out of date and turn bad?
