I have old tilt and turn windows which I'm looking to replace some blown units and renew some of the gaskets on.
Just wanted to check that I'm not being a dumbass, external gasket seems to be attached to profile, I can move the internal bead slightly with a decorators knife, do I need to just be brave and give it a bit of welly or is there more to it?
Internal and external pics attached.
