Possibly something like this....What replacement product have you set your eye on?
If it were mine, I would weld but only small tacks then flap disc the tacks flush, fill with a metal based 2 part filler, sand & paint.
With the windows out to expose the opening you'll be able to slide a sheet of tin or something down the back to stop direct contact with any insulation (had it been spray foamed?) and with small tacks in the 3 or 4mm cabin sides, there'll be barely any heat anyway. Bucket of water & a sponge or a spray bottle on hand just in case. Give the tacks time to cool a bit before adding more, start with a tack on each of the outer edges & work in towards the apex of the corner.
Most of the shaping of the radius can be done before tacking in place to save grinding sparks in situ.
If there is any slight deformation a tap with the hammer will sort it.
Should be fine.
lots of panels on vehicles are bonded together.....
I haven't used epoxy but have great results with Sikaflex, using it to bond steel and glass.....
u'll need to leave it once applied for 24hr's.....
once cured it's stronger than the material bonded.....
Sikaflex is the marine standard response, but very spendy, we just use PU XX and we have no problems above and below the waterline. I glued sterntubes back in after the mooring ropes have basically ripped them out, craning out in emergency situations €300 grand boats. PU even dries underwater.Is there a specific Sikaflex product you recommend?
I'm afraid I used the cheapest I could find on eBay, think it began with an "M" I'll have a look tomorrowThat sounds promising! Yes the boat has been spray foamed so appreciate I might need to strip parts of that off where necessary! Is there a filler you recommend?
Sikaflex was the industry standard, twenty years ago, then it just got copied by most PU companies. We only buy the UV stuff, not even sure why.I'm afraid I used the cheapest I could find on eBay, think it began with an "M" I'll have a look tomorrow
i bet you could buy tripple glazed for the price you would spend on marine glazed and thats in the same space as the aboveNo doubt about that, I imagine they're just standard domestic glazing with 12mm spacers & marine tacked on to make them extra spendy
The problem I had was fitting the glazed unit in a casement that doesn't then sit too proud of the cabin side or too deep into the cabin. Most cabin sides are 3 - 4 mm with an inch occasionally 2 of insulation between ribs and battens. Space is so limited that everything is balancing compromises hence double glazed but only a 12mm spacer.i bet you could buy tripple glazed for the price you would spend on marine glazed and thats in the same space as the above
This stuff sounds fantastic, like CT1 but affordable? I know that CT1 will cure under water, boaters often use it to close pin holes etc. but bonding a stern tube!! Legend!we just use PU XX and we have no problems above and below the waterline.

With the cheapest off eBay I meant the metal 2 pack filler that I used to fill & fair. The Puraflex is Toolstation for the odd one or specialist suppliers by the dozenSikaflex was the industry standard, twenty years ago, then it just got copied by most PU companies.

Don't do this! Total waste of money if you've not got the means to hold them in place.yes there is proper narrow boat windows on ebay but id rather buy proper guaranteed double/tripple glazed units

i think you might have got what i was saying crossed when i referencedDon't do this! Total waste of money if you've not got the means to hold them in place.
We complain about the cost premiums of marine stuff but domestic house building and boat/marine stuff are chalk & cheese. Until you know the issues associated with boats & that environment you can't find the effective work arounds. There are definitely products designed for the domestic housing market that can be used effectively in boats but one of the reasons there's such a premium on dedicated marine stuff is that it's designed to survive in a far harsher environment. Even canal boats that mostly have a relatively tame life compared to other marine craft, even they get bounced around in a way you wouldn't comprehend from the bank side.

Right, gottiti think you might have got what i was saying crossed when i referenced
dont buy ebay marine grade as theres no guarantee with them i know theres a large cost with marine double and tripple glazed but getting that guarantee is worth it otherwise you might as well buy single glazed product as you dont know when it will fail
