I think this is what came with my Nova / plastic zipper:

But... it might have come with my Yeti cooler (also uses a waterproof zipper). I'm not sure if I should use it as it says Silicone free--thinking I might have confused the two and can't find any other zipper lube.
What should I get, and where would I find it? I searched amazon for TiZip, but nothing came up.
What do you mean by the "docking end"? The part that moves?
Silicone-free is good in this case. Even if it came with your Yeti, that looks like perfectly good lube for your drysuit zipper.
