Your Jeep is awesome. I have a friend with a '59 Willys I would love to get my hands on. You mentioned you are military. Do you live at a base that has a hobby shop with an auto shop?
You seem to have found a good method for your body work. Just remember Bondo must be kept less than a dime thick or it will crack eventually. If you have a thicker patch get the bondo that has fiberglass threads in it. One method for patching if you don't have a welder is to cut a patch of steel a bit bigger and glue it from the back side with auto panel adhesive and fill the front with fiberglass bondo. The adhesive is about $20 a tube from Eastwood and is applied with an ordinary $5 caulk gun. Instead of real Bondo brand I like Rage Gold from Evercoat; it's about $49 a gallon from Eastwood.
