Do these have a shelf life? I have a set of front and rear plates that have been sitting in a tool box for about 10 years now. I am going to put a 904 together later in the year.

Kind Regards

I would call the company. But from my experience the major issue with shelf life would be moisture, if they were sitting in a cool, dry area out of the sun, they most likely would be OK to use, if they were sitting say in a box exposed to humidity swings like a basement or a shop that the floor sweats when the weather changes, I would not use them. I have pulled out new kits that have been sitting in the box for a long time and the fiber simply flakes off when you rub on them.
