Uretek water resistant zippers

I replaced the stock zipper on a rain jacket with one of these and was thoroughly satisfied. I wouldn't recommend it if the zipper was going to be over your head (as some leakage is to be expected) but in a beak application I think you'd be happy with its performance.

How much tension will they be under? When I replaced the seized zippers on an old MGB tonneau cover with these, Seattle Fabrics warned me they would not work under heavy tension and, well, they didn't even like to stay zipped, much less keep out water.

I think these are the same as the open-ended one on the OR Zealot jacket? If so, some cautionb is needed. We found that while the zip runs freely enough, and is moderately water-resistant, threading the (open) end together to start it is an absolute PAIN! You would not want to have to do this in the rain with cold hands of gloves.

However, if you want to use a single-ended one on the beak, it should stop most of the water and work reasonably well.

Cheers

ok, i think i'll give it a shot.
