What should I do with the sheeting on my kit thats is alittle wavey? The wing has some sheeting thats wavey, I am going to fiberglass the plane will this get rid of it or should I use balsarite to fill the area in. However that would take alot of filler! I'm going to use West Systems resin the finish off with evercoat filler! I was thinking the evercoat could fill in the waves but I don't want too much weight! What do you think?
