Companionway hood internal fillets

[DanaDCole]

It seems to me the companionway hood ought to have fillets on the inside as well as the outside. This should add a little to the strength and keep water from leaking under the hood sides. I'm not worried much about water getting in there because the bottom of the hood sides are sealed with epoxy--it just seems un-seamanlike, and I suppose mold and other things could start growing in there. (There are not many places water can get into because of the glue, but there are some spots where the hood sides did not quite touch the deck.)

I had thought I would just put 5200 sealant there with a caulking gun, but the opening is so narrow I can't get the cartridge spout to reach down into the joint. I suppose I could use a tube of 5200 instead.

Again, fillets would be best, but it sounds messy. I don't think I could control a "pastry bag" very well in there, so I would have to just transfer the fillet material with a putty knife or some other tool. I can lay plastic sheeting in there to catch spills, but I know I'll end up getting it all over my arms and elsewhere on the boat.

Has anyone else tried either of these? How did you do it? What works best?

I think I have accidentally solved this problem. After the reply to my other post about water infiltration I used a thick application of unthickened epoxy to fill the screw holes. Much of it also went down to the junction between the hood and deck, so when I realized what was happening I purposely brushed it on down there too. With gravity's help I think it did a fine job of filling in any tiny gaps that may have been there.
