Most Kayaks are not blow molded, but rotationally molded. When you look at
the weight of a typical polyethylene kayak, it is MUCH heavier than the same
type of part would be built using aircraft suitable technology.

At Dicks Sporting Goods I can buy a blow molded UHMWPE
kayak for $399.00. Thats half a fuselage with a very
smooth finish. Wings could be a box beam spar out of
Graphlite, sort of a rag wing design, with UHMWPE vacuum
formed or blow molded around it for the skin.

Not that I'm trying to put refinishers out of business.
No! There's
a lot of old ships that will still need refinishing
for years to come,
but the NEW ones should have surfaces that will never
need to be
refinished.

Oh yea, this glider of the future with the no-refinish
surfaces,
should have performance capability better than ASG-29/Ventus

LS10/eta/EB28, etc...
