After reading Mike James's post, I thought I will have to try it. I have constructed a ME 262 fuselage that I was going to strip plank. It would take forever, so I decided to give his method a go. I used masking tape and so far 2 cans of expanding foam. I always wanted to produce my own fibreglass fuse so now I will with this method. So far so good. It is a big fuselage so it will take a few more applications. As you can see from the pics, I will need to go back and do some filling in. I will add more as I progress with it. I am in no means in a hurry as I am constucting something else at the same time.
