Hello Stefano,
corrosion in salt water causes snug fitting aluminium or brass tubes to stay
together like hell. An old german folding kayak builder told the story, that
there where to classes of boats and owners in the old days:
The ones who used wingnuts and bolts together with U-profiles and kept spare
nuts;
The other ones where purists who didn't want the risk of loosing the nuts and
used mainly brass or copper sleeves;
At the end of the trip, when the wingnut guys had collapsed and packed their
boats, sometimes the sleeve companions were not able to take the first
stringer apart and got bloody fingers from slipping on the sleeve's edges to
get a grip on them.
---I have seen a russian folding kayak these days where they tried to compensate corroding with a very loose fitting of the anodized inserts, but corrosion worked it's way also through the anodized parts (I think, the boat was not used in salt water!!).
On my take-apart paddle, "Ballistol" weapon oil helped a lot to prevent corroding and keeping the sleeve going and it is not toxic. But I have a much better grip while pulling the parts away from each other when collapsing a paddle. If you use a fluid (MoS2 or similiar) you may be able to get better results but also black fingers ;-)
