After you paint, go to the auto parts store and by some small black fuel line hose split it down one side. You can see a thin seem line on the hose use that as a guide. I just pull it onto a sharp X-acto blade with thumb and pointer finger staying behind the blade very easy to do. Then use it for the open cockpit combing get it all on nice and neat first then pull it back here and there to add a few drops of medium CA. Now it's there to stay and looks great.
