for small segments, may i recommend,
don't use vulcaseal sparingly like superglue.
lather it on very liberally, like cake icing.
but clean the surfaces first.

but if it is for entire sheets,
for the best of me, i also do not understand why skylights leak so reliably often.
perhaps the material is too brittle for long-term water resistance strength...?
