I suppose there are some people, some where, who can apply glue or caulk from a caulk gun, but I ain't that person. I am lucky I didn't glue my eyes shut by this time. I ran glue in the seams, then came back and checked where there seemed to be gaps and reapplied glue, and on the 3rd pass, realized why I hate Duct tape. It was coming off the inside and the glue I was applying was just running down the interior. Use packing tape, not Duct tape.
