Humbrol acrylic Matt varnish spray - any probs? Milkyway?

[Noel]

Hi Guys has anybody experienced any issues recently with Humbrol matt varnish rattle can spray? I've used it for years with no problems but last two cans are consistently going milky in a way I've not seen before. Usual precautions have been taken such as the cans are stored somewhere warm not cold, applied in a dry warm atmosphere (eg not in a cold damp shed during winter), the target surface is well cured usually 48hrs after painting, and I apply in thinly in multiple coats.

I could just be unlucky with two cans from a bad batch. I also tried applying it direct onto unpainted plastic surfaces with the same results (ie going milky). I often do this if weathering plastic chassis as weathering paint doesn't take well direct to plastic, but a coat of matt varnish and both railmatch paints and weathering powders take to it better.

I stay away from Humbrol Varnishes these days, I use the alclad stuff now due to that very problem.
