i just need some help here guys. i know this is a basic question but unfortunatley i am not familiar with foams yet since i only recently started 12th scale and run only rubber in sedan.

anyway, what are the shore ratings of the following compounds:
-jaco green
-jaco blue
-jaco purple
-jaco white
-jaco gray

and do these color codes equate to what other manufacturers make? like, is a Jaco purple equal to a TRC pruple compound as well?

thanks!
