(See if I can make this thing work... old dog learning new tricks)
Was recommended here, so I tried foam backer rod. Seems to work fine. Think I used half inch, glued it in with silicone caulk and lightly closed the hatch to hold it in place until caulk cured. Get it at any lumber yard, get more than you think you need, it will use more than you expect. Easy quick and not expensive.Do it when you have a tube of silicone open for another job and you will wish that everything was this easy. Good luck! Ed
