I looked at the Sikaflex products but decided on a 2 part epoxy.
Russ how difficult was it to remove the old 3M trim tape?
I decided not to remove the frame but to squirt the epoxy into the gap leaving the 3M tape. Hopefully this will work if not then I'll probably do as you did.
BTW on a couple doors the previous owner had used a black (epoxy?) but had just smeared it on the outside of the frame and door. This did not work and that is what I'm reglueing now.
