I don't use bamboo. So for a furled leader floatant.....I spray an aerosol can into a container to get enough liquid. Then soak the leader overnight and let hang out to dry.

I use a can of "Silicone Water-Guard" from Wal-Mart.

Cap is orange with yellow sticker on top that says "Scores 100 with single application. Highest performance possible"

Just telling you what the can says in case you go looking for it.
