Ive used glazing silicone on the leaks several times but to no avail.
I'm wondering if the leaks is somewhere else and not where you think it is
The leaks maybe coming from the top somewhere
Is the leaks on every panels
Is it glass
The leaks on my upvc conservatory was a nightmare to find, I undid the glazing bar cover plate off as it was collecting the water back inside to the screw hole and dripping through the alarm cable, it's easier once you can find the leaks, I nearly gave up
I think a general clean down, replacement of the beading, resealing etc
is the best bet.
Maybe or you could be doing unnecessary work. If you're going as far as that maybe it's time to switch to metal or plastic glazing bars but a bigger job and more costs.
Just wondered if anyone had any other suggestions with best products etc to use,
Well if it was me, I would rub it down and use exterior liberon filler where its needed and run a sealant from beading to glass/polycarbonate sheet then use a few coats of Liberon Tung Oil - very easy to do, just rub it with a rag. I have an a open joint on my bay window sill and temporary use Tung Oil in the joint and no problem so far. China been using Tung Oil for years on their boats!
I wouldn't use bitumen type flashband, they're useless in cold weather unless you was thinking a difference materials.
I once jokingly said to my mate with the same problem as you, told him to stick a small gutter upside down, U-seal on the edge then screw it down with rubber caps. Never has any problem and no more painting, I'm still learning
Others may better idea
