Call me stupid or whatever else comes to mind! I did the bottom of my fuselage with the Cory Bird method except I only used 3 coats of pure epoxy. I sanded this smooth and had a few pinholes. If I had put on 5 coats of epoxy I do not believe this would have happened. I already had 1 gallon of smooth prime on hand so I rolled it on. Smooth prime directions say to apply 3 coats, sand, apply 3 more coats and sand smooth. Since I already had a pretty smooth surface after the first sanding it looks really good! Now for the dumb question, and no I do not plan to use the smooth prime any more. There are some places where the smooth prime is sanded through. Since I will have to apply a 2 part epoxy primer anyway do I have to apply more smooth prime to cover the spots? I am trying to save weight here and if I had it to do over I would not have used smooth prime. I am not a painter as you can probably tell. Any opinions here will be appreciated.
