Hi Ingemar

Sorry about your illness, hope you soon recover.

From your description, this appears to be "cob-webbing". Is the material
coming out of the spray-gun/nozzle like a spiders web? It may be the
material being too cold. How is it stored and is it left long enough to
stabilise to room temp?
