Runny glue for glueing stainless splashback in situ

[Atgni]

I have a custom bade stainless steel splash- back been in position for about 23 years. Its stainless steel contact glued onto OSB. It is coming away from the OSB in a section. from under the wall unit to to work top I need to somehow get some glue down from the top as I have a 5mm gap between the top of the stainless and the underneath of the wall unit.
I need a glue thin enough to be syringed through a thin pipe or thin tube bent at 90 degrees. Thin so it can run down to the worktop.
I was thinking a fibreglass resin but know nothing abut the stuff - any other ideas.
Thanks

I don't know what you could use?
I'd remove splashback then stick back on with a polymer grab mastic.

I don't think super glue like the thicker stuff you can get would work. May get messy.

PVA won't work.

Maybe fabric glue in a syringe but I'm not convinced

You might find the whole thing comes away from the wall if you give it a bit of a tug, if the adhesive has failed in one section, it's probably failed all over so might be time to reapply an adhesive to the whole thing.

Worked quite a lot on commercial kitchens the stainless steel wall cladding is fixed on the edges but mostly stuck back with the cheapest silicone that's available.

I built it and fitted it in place. Its osb screwed to the wall and then covered in evostick contact adheasive as was the stainless steel sheet and then the sheet pressed into position.
Its 2m x 500 rising to 800 high behind the sink and bends and returns at the end around a wall - I will get some pictures. I doubt I will get it off without putting crease bends in it.

I once repaired a steel splash back by screwing to background using decorative pig nose screws.Gives it an industrial look.

Never seen those before - thanks but the beauty on my splashback is that its easy to clean and those would make it harder to clean and look ugly.
But it has given me an idea to drill bigger holes in it right in the middle of the area coming away and then get some glue in there or maybe even ring shank nails something with a very flat top so I can then glue a whole new piece on top.

Its difficult to get a picture showing it because of the stainless steel so I have drawn a picture.
The blue is the stainless steel on the left is a bend towards the wall and on the right it is made to fit and bends around a wall before a winnow revel, its all one piece and I think was the 0.7mm thickness.
The black hatched area is the section coming away.
If I try to remove I an pretty sure that I will end up putting a kink in to it.
I could go for full on destruction removal but retain the right hand wall section and replace the large flat area piece.
But I really want to re glue in situ. The bottom of the hatched area has come away but the gap between the steel and the work top means I can not get in there but at the top I have a 5mm gap between the steel and the wall unit above. Just need some sort of thin adheasive that I can let trickle all the way down to the work top.

Ok slowly coming up with a plan.
From inside the back of the wall unit drill out a series of holes and make a slot and use a flat piece of steel I have spare to keep pushing down a polymer adheasive then I can clamp flat with wood from the other side of the kitchen. ( think - star wars in the trash compacter style )
I have used stixall with success on plastic sheets and its quite thin compared to other stick grabs so it does not show as high spots under the thin sheet you are fixing
