[TowerTalk] Nut & Bolt Sealant

[Gedas]

Hi Keith. I have a lot of experience with epoxies since I was a kid (dad 
was head of QC at a major adhesives firm)......I love the stuff but I am 
trying to stay away from a 2-part compound. But the properties of epoxy 
is what I am after, consistency and strength, cure time, etc.
