There are many problems with the foam you mention over the years. The
RV gear leg/fairing voids pumped with foam ended up attacking the metal
gear rods and pitting them. I imagine water or trapped moisture was the
culprit here. Foam can be hydroscopic and absorb moisture. Cessna had
problems with foamed elevators absorbing water. Your door fill area
might not be a problem area with foam, however I wanted to bring these
points up for consideration

Fiber Glass thickness at Door Bottoms.
Bob, I took an epoxy syringe from west marine and drilled small holes
above
the joint and pumped in thickened epoxy, then just filled the holes
(#30).
It Ended up making a fillet inside the door frame. I also pumped in
expanding urethane foam into the larger cavities to insulate and glue.
Just
be careful not to guppy the thing....the expanding foam can easily
deform
the door. It didn't add much weight but it really seems to give the
door a
more solid feel...
Fwiw
