I accidentally posted this in another forum. I purchased a used - but in good shape - MB pro dual fuel and want to seal the door. I have read several methods here but nothing definitive. A lot of ideas and " I tried this" are out there - I am looking for what actually worked best in the end. I am interested in the silicone gasket from Home Depot. Does it hold up? I also have a section of Big Green Egg felt left over from a different one. Could use that here too but I would have to cut it in half length wise (would make 1/2" x 1/8" sections) to make enough inches to do both doors.
