So, this case started out as a Roadrunner Express bag for an electric guitar.
It isn't finished yet but I will post the finished results. If I remember to take pictures during the process I will post those as well.
It required about 3 cans of the Great Stuff for windows and doors. I just started it Saturday and had to pick up another can yesterday and fill in the spots where the foam sunk and didn't cure in time. Not positive on the reason but I think it is because not enough airflow was getting to it. I might need a 4th can though. I was hoping it would only take me 2 days to complete but it looks like it might take me this whole week or maybe I will finish it by Wednesday. I have some 3M adhesive spray that I will use to lay some felt cloth over the foam after it is carved out for my rifle, mags and maybe if I have the room, a pistol and a couple mags. I have not decided on the color of the felt yet. Hopefully everything will come out nice in the end.
This is a stock photo of the bag.

Here is how it sits at the moment waiting to cure. I will have to see if I need to add some more foam to it when I get home. The photo was taken when I went home for lunch.
