For a while until the 3-in-1 causes the seals to expand and/or perish. A
light smear silicone grease is the stuff to use.

I paused at that suggestion. Then realised that if the seals are
neoprene, that is supposedly resistant to mineral oil. And PVC is pretty
resistant too. Found this relating to one PVC sheet product:

So I ended up being perhaps more questioning over its effectiveness
(will it really get to the right places?) and the possibility of
splattering oil over whatever is underneath the guttering.
