Now your on the right track! Of course the repaired wing be on your mind, and the fear is ever present. but if you get it back in the air it's your bird! not something put together by whomever. use the repair bird as your knock around bird.
The fear of crashing and the desire to look good is a anchor around your neck and will always be that negative that keeps you from venturing forward and taking that chance. The best looking whatever isn't worth that hill of beans if it doesn't give you the satisfaction of knowing you did it. success or failure isn't important it's the journey that counts.
OH! and yes you can produce the good looking finish on your bird. you just need to start somewhere!
