Right, now I have much experience of using both these glues, but not in the field of submersibles.  I am gluing the deck planks to my fibreglass darnell deck: am I wise to continue with cyano or is there some terrible punishment waiting for me later on that means I ought to use epoxy?  It SEEMS to be adhering very well to the bare fibre glass skin, but...

Water can effect some of the cheaper superglues.
Do a test. glue a bit of wood to a scrap piece of fibreglass and leave in a jar of water once dry

Ok.  Its not cheap, its the Zap medium

Good test: I'll do it!


In fact the whole lot will be varnished prior to submerging because I dont want the wood to get water logged and swell.  I intend to paint the lot with thinned varnish prior to painitng the timber in kriegsmarine wood treatment as issued by UBootwerkenSalisbury, No 2 dock..  (AKA black paint!)

I'm probably a bit "belt and braces" but I tend to steer clear of both cyano and anything quicker setting than 24h epoxy. If it is critical bond to fibreglass I would prefer to bond it with polyester resin i.e fibreglass it in. And I don't like wood at all for construction unless it is essential. Sorry just my views  but submarines are a bit unforgiving

I used modelbond superglue on mine, no problems. I presume you're painting it with halfords paint too, which effectively plastic coats it, so I wouldn't worry too much

I wouldn't class ZAP as "cheap"!!!

On the recommendation of many fish keepers, I used to use Loctite Superglue Gel to glue coral fragments to rock in my Marine aquarium.  On one occasion, I realised I'd glued it in the wrong place and broke it trying to remove it - after 3-5 minutes.

You could try giving the wood a couple of coats of epoxy resin before painting.

It tends to be thinner than polyester resin, and thus penetrates the timber better. If you're thorough with your preparation it shouldn't be a problem, although water pressure will ensure any areas missed will soon make themselves apparent.

However if you're going to paint it black, why not use plastic strip in the first instance?

Thanks guys.  I could have used plastic strip but it never occurred to me: im a trad modeller and wood jumped out.  Also at 1/8 inch it is scale for the deck timbers, or pretty much anyway.  Further, the thickness is the same as my waterjet cut grilles, so the whol deck builds up smooth.  Further yet, I can weather the timbers to make them look like, well, timbers!
