Progress report, I worked on the little shark some more. After sanding the first coat of z poxy y applied silkspan with z poxy to the fuse and tail also the flaps and elevators. I used a brush and painted thru the dry silkspan, I did one side of the surfaces at a time and I used playing cards to squeege the excess z poxy from the area I covered. I give the z poxy a day or two and when everything was dry I hit everything with 220 grit sandpaper using the light of the sun to see the low spots and areas that needed more sanding being careful not to go all the way to the wood. I sanded my fuse before gluing it to the wing. I reinforced the center section of the wing and proceeded to cover the wing with SLC. At this time the weight of the plane without the elevator pushrod,tank, engine and landing gear is 8.4 oz. My engine weights 6.43 oz which totals 14.83 oz. If I go all the way to 20oz total whic I will be trying not to the wing loading would be about 10oz sq.ft. I will be priming the fuse and wings with Transtar 4633 white primer. I like it because is not hard to sand and is formulated to be used on flexible substrates. I have not been using it long but I used in the SLC covered wings of my P-51D profile and it worked good. well I used it in the whole plane. here are some pics.
