My airplane has Stits STC, but I am now leaning toward good old Ceconite/nitrate/butyrate. There have to be about a billion different STC numbers for Ceconite fabric, including my favorite process. Anybody got any idea of the history of these things?

My contribution is that the current STC for the above process is SA 4503 NM, but that may have started out with different numbers for different fabric weights. Super Flite (Cooper) had been around for a long time, and in 1963 each airplane had a different number, e.g., the J-3 was SA4-907

My Decathlon has the Ceconite process on its type certificate, except that you have to use something similar to Pliobond for fabric attach - so STC numbers are not applicable. But I am guessing that if you want to skip the Pliobond, the STC would apply.

And another random thought, although not really important - say your Cub was altered to Ceconite. The second time you recovered, would you check the alteration box again, or just the major repair box? Nobody would care, but it is interesting to think about.
