Roberts,
I used Koverall on my TF Elder. I used Stix-it for adhesion and it worked pretty good. To stabilize the fabric I used Deft clear finish. From the label, it looks to me like nitrate dope in a spray can. It went on easy and I had no problem painting over it with acrylic paint. I used Lustre coat clear to fuel proof it. Nice finish and so far no problems.
I did apply both the deft and the lustre coat outside. I don't think we'll ever get something that doesn't smell for fabric covering. Good luck.
