A picture would be helpful. So many different types of seals. Some clip on, others snap on, some have a self-adhesive strip and still others are simply glued. If you are positive you have a glued type of seal you can use
3M Supper 77 Adhesive Be very prudent using it...it sticks well and not easily removed if you tack in the wrong place.
