Lotsa luck on that one. Trying to identify by color without knowing the manufacturer is almost hopeless. A Shore hardness tester is about the only sure way to determine the durometer. If you are fairly familiar with the different durometers you can kind of tell with your fingernail. I use 90 and 95 for strippers from about four different makers and their compounds vary enough that it is tough to determine without a tester or knowing who it is from.

Good luck Les
