Some may not be, some I think are. The one I used specifies boat
repairs as one of its jobs and was sold to me on recommendation by a
specialist fibreglass boat builder. Mileage varies...

I'm not a chemist, but I did once research the commercially available
fillers on the market and at the time - three years ago, there were
none that were waterproof. They all use a filler material to bulk out
the mix, usually talc - which absorbs water.

It may be that there are some specialist fillers but you would need to
be sure that what you were buying was the right one.

Me Again.
This time I may proof read this.

I followed Richard Hayes instructions pretty much to the letter.
I ground the beast out with a Dremmel and found the cracks much deaper
that I previously thought. I ground through the boat in two spots.
I put some packing tape inside he hull to keep things in order as I
worked the ourside and got the gouges filled.
It is not going to be perfect but it is not bad.
I had about 10 yards of 10 Oz Fibre Glass cloth left over from a canoe
I built a long time ago. I used a little of that to reinforce the hull
under the repair.
Seems to work.
I am wondering how you get a reasonable gell coat back on there or do
I just paint it.

Right now I am not sure but I should just have reinforced the inside
and painted the begger. I am told I shuold have just left it because
it can last that way for years and only requires that level or repair
when it actually starts to break down

During my efforts I found another less pronounced star crack around
the skeg box.
That one I likely deserve as I remember one drop os some consiquence.

Are the NDK boats prone to star cracks?? I have one other glass boat,
It has one well deserved crunch but no star cracks. It is much more
flexable all over. The NDK has been babied.
