Hi Aric,
         Have you checked the fluid out on plastics yet? Some oils 
swell polyethylene by 10% or so and one that is used in commercial 
caps by a company here actually reduced hot melt to sludge, much to 
my horror. In fact they were using polypropylene in their caps so 
that result didn't count as far as they were concerned.
