I want to make a so-so waterproof deck-bag out of old day-pack. Is there
anything in liquid or spray that works, and not too exotic - can't mail-order
such things into Canada (wouldn't make economic sense either). Tried 80/20 mix
of turpentine and silicon sealer a while ago on old nylon sprayskirt, - it
helped, but the smell from the bowl was terrible.

Alex, I bought some clear "Shoe Goo" from the local sporting goods store. 
It's similar to "Seam Grip" which I think is polyurethane, not silicone.  I 
spread it on the inside of my (formerly goretex) spray skirt using an old 
credit card.  It worked fine, was low cost and doesn't smell bad after it 
dries.  The down side to this is too much folding / flexing makes it leak.

 Another approach would be to make a waterproof bag to insert inside your 
deck bag.  This could be sealed with "Shoe Goo" or instead use waterproof, 
heat-sealable nylon.  The advantage here is this inner bag can be discarded 
and replaced after a season or two if it starts to leak.

How about latex paint? Any paint or varnish would probably do the 
trick. Thin it down for a little more penetration. I would go to the 
local hardware store and see what they have in stock. There might be a 
concrete sealant that would work.

I thought of concrete sealant, because already have one - Thomson Water Seal
for wood and concrete.  Only somebody told me, that it was cancerogenic -
but
then any such impregnant is, except, may be, silicon-based ones.

Alex,

Don't be so quick to listen to others. Many people think all chemicals are
bad and harmful (totally forgetting that everything is composed of
chemicals). Here's a link that I found in about 5 seconds that indicates any
possible health risks of Thompson's Water Seal.

Thanks; useful link.  It would be really odd, indeed, if water seal for
house decks etc, in frequent contact with bare feet and/or hands, would
release much cancirogenic substances after drying.  And this water-seal has
been quite a long time on the market.

For the cost of these nasty coatings, you could buy a meter of 
waterproof nylon and sew it into a servicable underdeck bag.  Seal 
the seams with Aquaseal or seam sealer (forget which brand but one of 
them is really good - used it one a tent 7 years ago and it's still 
going strong).

Instructions on KayakWiki under Kayak Modifications/Knee tubes and 
Shelves:

<http://www.kayakforum.com/cgi-sys/cgiwrap/guille/wiki.pl?HomePage>

NOt explicit instructions, but guidelines and ideas.

An underdeck bag will be drier than a deck bag if your kayak has the 
room to suit your needs.

Alex,

I'll second Steve's assessment.  Here is the statement off the MSDS regarding 
carcinogenicity:
      "Carcinogenicity: MSDS: The ingredients in this product are not 
identified as carcinogens by NTP, IARC and OSHA."


Further down it identifies the ingredients as a collection of organic 
solvents (pretty close to mineral spirits --  aka paint thinner) and paraffin 
wax.

You could make your own Thompson's by dissolving a couple candles in a gallon 
of paint thinner, and save a few more bucks, Alex.

Suspect that the silicone sealer in a less smelly and perhaps more
volatile solvent - e.g. white gas/naptha - may be a better bet than
latex paint or varnish.  Latex paint and varnish are formulated to be
used on solid surfaces, and therefore will not have much resistance to
flexation when dry.

Bill's suggestion of a 'Shoe Goo' product might work - again if it is
thinned with some type of non-smelly solvent to allow for better
penetration.  My experience years ago with Shoe Goo was that it was a
very thick product, and therefore hard to apply.  Since it hardens by
evaporation of solvent(s), thinning it out a bit more may make it more
useful in such an application.

Haven't tried any of these ideas myself, just thinking out loud.....

Play Hard,
Erik
