Frank,
         The JB-4 kit is sold in the United States by Polysciences and they 
have wonderful technical help in the form of "Polysci Pam"
(AKA -- Pam Marcum) at pmarcum@polysciences.com.
         I have also used a kit called Technovit 7100 by EBS Sciences. Both 
kits work well for 2 micron sections. Hopefully you are not located in the 
southeastern United States as we are having major problems with rain and 
humidty....real problems with glycol methacrylate polymerization!
         Good Luck,
         Linda
