Re: Replace seal fiberglass sidelight?
Does the "seal" look like double stick tape, probably foam core? This is the current fad for window installation. If this is your case, then simple cut the material along the edge of the frame with a sharp utility knife, then using a single edged razor scr-aper, remove the material from the glass.
If the "seal" is rubber, then either leave it or disassemble the window and readjust the material.
