Brief Description: Tie down hook and dimpling of RR#5-6
I removed RR#5 and RR#6 to drill all the holes to #20, dimple and coat with Cortec before re-installing. While I waited for the Cortec to dry, I decided to mark the position for the wing tie down bracket, a little fiddling and measuring and it was mounted, the wworst part was drilling the slot in the skin and filing it smooth, I ended up right next to the rib which made the filing a little difficult, but the end result was quite good.
