Ok, I finaly had some time to assemble the plane and fill the gaps that were large. I really dislike putty. I even sanded the seams and tried to make everything smooth. I grabbed a large box to spray in. I set aside Sunday afternoon to paint. I hung the plane inside the box to spray the primer and nothing comes out but air

What is wrong?
As for the plane, I found a photo of a F5A that I can paint and not have to worry about the purchasing decals. The colors may be a little off but since this is for practice and I do not want to spent any money on it. I am looking forward fo finishing up so I can paint the B-25.
