thank u. i say im a beginner. i built a dumas hotshot 45 hydro years ago and had a blast. loved building and still do, but that was long ago and havent built any models since, well till now. i was pretty sure i needed to sand radiuses, but green i am and away from the hobbies many years. a wise man will say i dont but a fool will just well. thanks again to you all for the help.
