Hi all, i'm trying to remove a upvc door panel (haven't done this before) and all advice I have had makes me feel this should be pretty straight forward. I understand the principle of detaching the beading surrounding the door panel but the beading is so tight against the door frame I can't seem to get any tool in the gap. Have tried wallpaper scrapers, flat head screwdriver etc. I have also tried pushing the beading to make a small gap but the stuff is pretty tough and won't budge. Is there something I'm missing? any suggestions greatly appreciated.....
