Date: Thu, 5 May 2005 22:16:09 +1000
G'Day,

Some years ago I bought some patches made of a black sticky material backed
with foil, for patching holes in kayaks at sea. I'ld like to buy some more
but can't remember who I bought them from. Does anyone know where I can
purchase such patches?

Thanks and all the best, PeterO

Would that be Bituthene, Miradry or Denzo tape?  I've never heard of 
these until fooling around with Kayak Wiki, but these match your 
description.  It looks like plumbing supply shops are a place to 
start.  Otherwise, Google is your friend...

Black, sticky, foil backed....makes me think of flexible adhesive flashing 
materials used when installing windows in residential 
construction.  ProtectoWrap is one brand.  Grace Vycor is another 
manufacturer/product line.  Stop by a good building supplier and you can 
buy it in rolls 4", 6", 9", and 12" wide.  Sticky stuff.

Or...stop by a construction site when you notice they are installing the 
windows and grab the scraps for free.

Or, you could just order a kayak with a proper expedition lay-up in the 
first place. :-)

G'Day Doug' Richard and Paddlewise,

Thanks everyone for all the suggestions - Looks as if I'll be hanging around
building suppliers for a while, searching for the mysterious Denzo tape - it
sounds like the material I'm looking for, just need to translate it into
Australian:~)

Richard - My experience with duct tape is that it doesn't stick to wet
fibreglass. I'm looking for a quick on the water repair when paddling along
non landable stretches.

Doug' I'm guessing you mean polythene kayaks! :~) Last trip we had three
minor boat casualties - perhaps the wisest words you will hear on Paddlewise
this week - don't try to sail through gauntlets! :~)

All the best, PeterO

Well, real paddlers don't paddle polythene plastic, though my Tupperwear 
sandwich container has admittedly proven durable over the last decade of 
lunchtime abuse. :-)

Incidentally, I was out last Sunday for a paddle around an unfortunately far 
too mild Race Rocks with some fellow fibreglass (and wood) enthusiasts. One 
of the gang was in his brand-spanking new P&H. A virgin hull! How quaint. 
What a sight for sorry, old eyes like mine. Anyway, he had been going to let 
me try out the new Quest, but after seeing me run my old Nordkapp up over 
one of the worst looking razor-sharp barnacle covered rocks anyone has ever 
seen, he declined further offer. Of course, I picked those rocks 
specifically, as they were so dramatic looking, just to prove my hull could 
take it. And the shock value is kinda fun for those who haven't paddled with 
me before. Of course, for my troubles, I was labelled a "Cowboy" by the more 
senior of the BCU followers.  Ya hoooo!

Hey, we had a great time after the main paddle playing at towing, rescue 
drills, re-enters, etc. I was getting dizzy, so sat-out the last of the 
on-water activities which was a simulated hull-repair scenario, but 
apparently they did get the duct tape to stick just fine to the wet hull of 
the rescued boat. Seems to matter what brand the tape is. Also, as for the 
Denzo tape, I have been on a remote paddle where there was some hull damage 
to a boat (not mine, of course!), and the Denzo tape didn't work well at 
all.

BTW, it was interesting observing these inspiring paddlers I was with. All 
are working hard at improving their skills, taking courses, following the 
most excellent BCU way, and replacing their kayaks with designs that promote 
more lively and subjectively more fun paddling. The wrong kayak can sure 
limit one's progression in the above mentioned direction.

I took the time to work on my offside roll and sculling up/deep water 
sculling, all with my bad left shoulder - which I don't usually practice 
with. Probably not for the last twelve years. It all came back instantly, 
like I'd never not practiced. But I paid for it that night, and the next. 
Now, can I get a plastic joint replacement for my shoulder?

G'Day Doug,

"Seems to matter what brand the tape is". This must be the key to contrary
results with materials for repair! Theres no way any of the duct tapes I've
tried would stick to a wet fibreglass hull - but maybe what I've used isn't
true duct tape. I haven't tried the "Denzo" or "Denso" tape yet. (Thanks Ron
for the antipodean spelling).

As a digression on a topic related to the brand of protective materials. A
few months ago we were discussing helicopter tape to protect against keel
damage. Again the brand must matter because the general opinion was that
Helicopter tape wouldn't give satisfactory protection. I was suprised then
last weekend to see an example of 3M helicopter tape in very good condiion,
that had been on the keel of a fibre glass boat for two years. The boat was
routinely dragged across sand and run up on to sand beaches. Mostly
Australian beaches are sand not pebbles and it wouldn't have stood up to
oyster beds - but for protecting against regular landings on sand the 3M
tape seemed a very good solution.

So the brand seems to count hugely. Do you know what brand of Duct tape was
being used for the in water repair?

Perhaps Aussies should buy their duct tape from the US and Americans get
their helicopter tape from Oz!

All the best, PeterO

US$125 a roll!!!

I think I'll stick to using gelcoat (+ or - cabosil).
