Andrew, My advice is to take it seriously and wash very thoroughly and then 
wash again. I think the release agent is just a water soluble thing which 
will be there in small quantities and not necessarily visible. My reason for 
saying this is that release agents contain a chemical known to be good at 
enhancing or provoking the production of allergic reactions. I was a bit 
casual about the washing as it looked reasonably clean, but I developed a 
serious allergy, giving asthma and most unpleasant lung and nose symptoms 
whilst dry sanding the wing and fuselage smooth surfaces to prepare for gel 
coating, which like paint needs a matt surface without any trace of shine, 
(and it is potentially lethal, since repeated exposure once sensitive can 
give anaphylactic reactions) I am not sensitive to ordinary fibreglass or 
filler dust but only the dust from those moulded surfaces which  have been 
coated with releasing agent.
           Regards, David Joyce, G-XSDJ
