[TowerTalk] Installing and tensioning guywires

coating stays useable if the grips are stored in the box on the shelf for  
years before they are first used.

    I'm not sure what the official company policy is  but I wouldn't 
personally have any problems using old PreForms. As long as the  grit inside the grips 
is there, you should be good to go.  


There is no shelf life to grips if they are stored properly (dry/shaded conditions).  And I don't think that the main gripping is done by the grit in the inside; it's done by the Chinese finger torture design.  My belief is that the three month limit is that once they are wrapped in place, they develop a shape memory and may not provide the same gripping ability. The grit inside is just some gravy that is added.
