Default Fiberglass Tape: Holding To A Curve?

Several tricks that might help:

Thicken the resin a bit with colloidal silica
Accept the help of gravity. Point the boat part nose-up.
Instead of selvege-edge tape, use cloth cut on the bias. It conforms better
to irregular bends .
Cover the wetted tape or cloth with peel ply (a nylon taffeta fabric). Cut
the fabric extra wide (6-8") and pull it taut across the joint with duct
tape on its dry edge. The peel ply can be peeled off the glass after the
resin has cured. In a pinch, nylon taffeta from the yard goods store will
probably work. Test first that it can be peeled off cured epoxy.
(This is iffy. do it only if all else has failed.) Coat the joint with
epoxy resin and let it kick to the sticky stage. Apply your cloth dry at
that point. Come back later and saturate the glass.

1" tape, covering a hull/deck seam on a surf ski. Epoxy resin.

Somebody suggested using wider tape, but the original stuff was 1" so I

stayed
with that size.

Looks like it's going to go on ok except up at the duckbill/hammerhead bow

where
there's a curve that it has to follow from center to edge. Think trying

to
tape Donald Duck's bill closed by running a 1" strip from his left jaw

around
the front and over to his right jaw - following the seam of the upper and

lower
bills, but wrapping around top and bottom.

Maybe it will go on ok, maybe not..... But just in case...

Are there any ticks to get glass to adhere to a close radius outside

curve?
