Pam asked about repairing a GP

Duane really said it all - use a marine epoxy (eg: West Epoxy).

If there's a lump missing from tip or edge, smooth out the face of the wound
and fit (hand carve) a small lump of wood to glue in. I like shaping the
repair to look something like that first bite in a sandwich - an arc. Maybe
avoiding hard corners isn't necessary, but to me it looks a little nicer (as
there aren't many hard corners on a GP). Match the grain if you wish - or
make it a contrast to emphasise the 'patch'. Glue and let cure and then
shave down to match the surrounding wood of the paddle. These repairs are
easy and have worked well for me up to about 50 x 20mm (so far).

In the case of a big break - further up the shaft - I broke one paddle and
never managed to repair it satisfactorily. I was trying to fix it 'quick &
nasty' which is probably why... I didn't much like the paddle, so I soon
gave up and made a better one. At least the process gave me a better
appreciation of how I wouldn't field-repair a GP ;-)

I should also point out that the breakage occurred because I'd been too
clever and taken too much wood out from the shoulder areas of the blades. It
was strong enough for paddling - although it offended the eye a bit - but it
wasn't strong enough for abuse. One learns... 

If I really wanted to fix a break in the loom (or in the blade near to the
loom), I guess I'd try splicing in a new bit of wood, using a good long
scarf joint and some form of jig (to keep the bits all properly aligned,
like a leg splint) - which you could make using the unbroken end of the GP
as a pattern. Hasn't yet arisen, luckily.

Since I oil my GPs, I use a hardwood edge and tip (in preference to Duane's
glass or carbon reinforcement) - just because under oil the fibre will not
look as pretty as it does under epoxy.

The only GPs I've epoxied all-over are the ones I took to Alaska with the
Feathercraft. I found that our oiled paddles chafe too much with the FC -
the deck ropes are right on the edge of the hull/deck and the paddles rub
there when we get tired & sloppy. The epoxied GPs slide on the rope & fabric
just like a slick 'euro' paddle shaft.

How do you all deal with the little wounds to the epoxy covering layer that
lets in the sea water and causes little 'ulcers' to bloom ?
