Re: Battle of Britain - Air Superiority: Nerd Herd Group Build

Can you explain this a bit more. What is strip PS?

After reading Shep Payne's awesome book he recommends thining the inside of the fuselage and then twisting a knife to model bullet holes. Would you put tin foil (aluminum foil) insde the plastic fuselage to model the torn insides? I guess I need to learn more about Spitfire construction.
