    Try the link I just pasted above. I just got it directly from the video on You Tube. You can also find the video on the Stewart System’s website. Note that according to the narrator the original topcoat can be used on a minor repair, but on a major repair, the STC requires the use of the SS topcoat.

    Thanks for all the feedback, again the original question was about using Stewart's Syst thru primer then NO topcoat of any kind. The goal was to not mess with 2 part systems and stick with brushing only.

    The work is not complete yet, but we already had the materials for both Stits or Stewart's (we've used both of these systems in the past on various aircraft) so in the end we decided to just use Stits (Poly Fiber), as the rest of the plane utilizes this system.

    Steve, to address your question:
    Why would you want to recover those areas? I have seen the paint etc crack and look bad.
    These areas have been giving us trouble for years. The paint is not in good shape and I did use the Stits rejuvenator a few years ago as well as re-taping a few areas. In the past at some point, somebody installed quite large rectangular aluminum inspection panels near the wing roots just forward of the flap cove, these drum in the prop wash and do not have a particularly good reinforcement on the fabric. By starting fresh with new fabric we think we can get better adhesion to the structure and install traditional (round) inspection panels. At the same time, while these patches of fabric are removed it will give better than normal access to really inspect the fuel system, wing roots, etc.
