Practical Chemical Information Sought

[SK Khew]

Hi Chris,

What you could do is to dissolve the napthalene crystals in petrol and 
then paint the mixture onto the butterfly bodies.  You could even put in 
a few other chemicals for an added measure of protection.

The petrol evaporates and leaves behind the fine white crytsals of 
napthalene on the bodies of the specimens.  

Should be easy enough for you to try, as long as you don't smoke when 
mixing this cocktail.  :-)
