JUST TOOK OUT SLIDING PATIO DOOR AND PUT IN FRENCH DOOR. WHAT IS GOOD TO FILL THE GAP (1/8″ TO 3/8″) AND ABOUT 4-1/2″ WIDE. BEFORE PUTTING ON OUTSIDE TRIM, SHOULD I FILL OPENING WITH GREAT STUFF INSTA-FOAM SEALENT OR SOMETHING SIMILAR? PROBABLY TOO BIG A GAP FOR CAULK. ANY SUGGESTIONS? I COULD SHOVE WOOD STRIPS IN THE GAP. I WOULD LIKE TO GET A GOOD SEAL. IT IS A PELLO DOOR WITH WOOD AND METAL MAKING UP THE OUTER FRAME. THANKS FOR ANY SUGGESTIONS. FRANK S.
