Shot in the dark tried searching and find some spray products but want to read from someone who's done or had it done.
Pent style conservatory/sunroom roof rubber seals on the polycarbonate under roof struts has perrished over time and rain is working its way in.
What spray sealant would be suitable to use in a garden manual pressure(5lt) spray or electric spray gun, albeit a pint size bottle. Searched can't find suitable. I want to use it to seal off the edges of the polycarbonate sheets at frame strut edge where the rubber seal has perished, as temp measure until fund is big enough to pay for a new roof.
Many thanks in advance .
Note: can't remove capping over glazing bars/struts if they break I can't replace.
