You have to have alot of patience. I started mine about a year ago and im still not finished. Just make a skeleton out of MDF and just wrap it in fleece and staple it then glass it and dont be cheap with the resin then bondo it then sand and sand and sand and paint it or wrap it if u wrap it u dont have to sand as much just make sure its kida smooth no lumps
