On my 3yr old french doors the thin rubber gaskets next to the glass have started to erupt at the bottom in the corners.I think I could probably correct the fault if I could remove the mitred retaining fillets but seems to me the only way to get them out would be to prise them forward which means levering against the glass.Any guidance ,much appreciated.
insert a thin rigid scraper inbetween the bead and frame and push the bead along the face of the glass.
start in the middle of one of the longest sides
