Norm, I am not adding that many coats. I have two cross coats of primer which is my UV coat and then two top coats of paint. I'm more concerned with weigh on my prototype than I am UV protection. I plan on stripping the fuselage fabric and rebuilding the wing and landing gear carry through frames. The wings will be new, so I'm not worried about long term UV protection on them. But here is what I ended up with for one wing, the total cover weight with Ekobond is 24 oz. (1.8 oz/yd sq dacron) The paint added a little under 2.5 lbs per wing. So working backward that equates to .015 lbs/ft2. for finish or a total of .024lbs/ft sq
