Scotchbrited and smoothed all the edges on the skin and ribs, cleaned these parts with detergent, did the usual, deoxidine and alodine. Once dried I primed the parts with grey primer (Couldn't get the white), also primed the inside skin where the parts will meet. I then riveted the ribs into the leading edge skin. Seems a lot quicker in doing the right wing, as it is a repeat of the left most of the time.
