Try the 30 minute, 2 ton devcon instead of the 5 minute Holds up in water better and won't yellow as quickly. Or, if you like etex better, go with that. They also make that same cord in silver and gold if you want to experiment further.
Where did you get the devcon? I looked at homie's and the craft store and didn't find it in either one.
I think i might have seen some in the flyshops?
