There is a lot of dings on the under side and a hole from the switch for the glow plug, what is the best way to fill the hole and dings. I don't think I'm going to sell I like even more and the more I look at it the more time I spend on fixing it. The wing does not have a mark on it but the tail section had a repair and needs to be redone. I hope to have it striped down by the end of next week I will post pics and ask a lot of questions.
