OT: Installing a vent plug?

I've got a waveski on order.

Maker says they use a higher-density styrofoam that doesn't need a vent plug.

My reaction is that I'd rather not find out if they're right or not on a hot
summer day when I forget and leave the thing in my vehicle... or if/when I
airship it somewhere..... So I'm planning on installing one myself after I get
the board.

Doesn't look like rocket science to me:  open up a hole, stuff the thing in with
epoxy and a little cloth around it, trim excess and sand - making sure that the
epoxy hasn't wept into the hole at the bottom of the plug and blocked the air
passage.

Is there anything else I should know?

Or should I just lean on the waveski maker to put one in anyhow?

I'd not add the fiberglass, and I'd probably use to J-B Weld Epoxy.  
It sets up quick, is readily available, is usally fresh on vendors
shelves, and is easy to control so you don't make a mess on surfaces
adjacent to the vent plug.

JB Weld? (!)
Why not do it properly... the same as installing footstrap inserts or
mast/fin boxes.

Set in expoxy mixed with Q-cell or microballoons. Add enough filler to make
it about the consistency of yoghurt. Glass over with 2 x 4oz cloth and
epoxy.  Obviously you would have roughed up the area the glass is to cover
and ground out a bit so you can blend the glass job in nicely.

So: the vent assembly would be inset a little and the 2 x 4oz cloth would then
go over the assembly - hole and all... only tb trimmed to open up the hole after
the resin has started to gel?

Sounds like you'd void your warranty.

Vents come in a few styles.  Most on windsurfers end up flush with the
surface of the board.  For a kayak, where stepping on it isn't an issue, I'd
get the kind that protrudes above the surface.  That kind usually has a
"tab" on the***so you can tighten/loosen by hand.  And you don't have to
go through all the glassing issues.  I'd use epoxy resin mixed with
microballoons as above, and just use it as an adhesive.  Put the vent in a
place where you aren't going to whack it with the paddle or otherwise stress
it and I'd not worry about going to the trouble of glassing it in.

My suggested solution was based on using a  protruding model R62-5119
plug from Fiberglass Supply.  http://www.fiberglasssupply.com/
Product_Catalog/SurfSailcom/surfsailcom.html    There is no real
stress on the vent plug so it doesn't need to be fully recessed,
glassed-in, color matched with Imron, then clearcoated and deck
dusted. Just locate it where it won't get whacked by something. If you
have West System epoxy and microballoons then go for it, but if you're
buying epoxy for this task it doesn't make sense to buy a quart of
West System, Hardner, and microballoons to put in a vent plug. J-B
Weld is a perfectly acceptable solution for the plug model I've
indicated and the peanut butter consistency is easy to control. It is
a good idea to roughen up the bonding surface of the vent plug with
sand paper before setting it in epoxy to increase the bond strength.

Sorry no insult intended. Just that it could depreciate the board / ski a
lot if it looks shoddy. Not knowing the guy's skills etc I thought maybe I'd
tell him the right way first and then "but if you have limited funds /
access to a friend with repair gear for WS boards, then JB Weld..."

Anyone who sails in more than 8kn should have the smallest (half quart?)
west system and some glass all the time, now we have widestyles  ;-)

True. Maybe get *in writing* that it doesn't need a plug.... then after
coupla years do your best to delam it and claim a new one.....

No offense taken. Your post reminded me there are a lot of solutions
to any
problem and I need to be more specific if I'm going to be helpful to
those
who need help.

So don't buy a quart of resin...  Buy one of the West 101 repair
packs.  Everything listed about for about $10.

I agree.  If it ain't broke, don't fix it.  If the vendor says it
doesn't need it, why do it?  Why put another potential leak in the
board.  And if you do have a problem down the road, now you have to
explain this vent plug.  I would at least hold off on it until the
warranty period runs out.  There have been plenty of boards over the
years that haven't had vent plugs.

I didn't want to be worrying about leaving it in a vehicle on a hot day and
forgetting to crack the windows... that and air shipping if/when I ever get a
chance to go somewhere warm.

After reading everybody's comments, I put it to the maker and he's gonna add one
of his own for fif*** bucks - which seems like a deal in light of, say, $5.00
for a plug, $10.00 minimum for resin, $15 for shipping... and so-forth.

Pete,
Ask the manufacturer if the foam core material is "extruded styrene
foam", if so, it's closed cell foam, and they are right, no vent plug
is required at all.  Actually, in closed cell foam core costruction, a
vent plug will do nothing.  This foam is higher density, and may be
what they are calling "higher density styrofoam", approx 2.2 lbs/cu
ft. as opposed to "expanded polystyrene" (common in modern windsurf
boards) which is approx 1 lb/cu ft.  I have made many windsurf boards
with extruded styrene cores and epoxy layup with no vent plugs, no
problems ever on airlines or in the sun...
