I like the spent fabric softener sheets from the dryer because it can be rescued from the laundry room garbage can, its very strong but with a really soft feel, you can squeegee the AQS right thru it, put a piece of plastic bag over the area and roll it flat
another good backing material would be super thin nylon, like the really thin nylon that running shorts are often made of
sometimes you can go with out backing like i did on page 1 to repair super thin gortex pants, to do that you would tape the outside, squeeze on some AQS, cover with plastic bag, roll it out flat and let cure
and just to clarify I don't use steel wool with epoxy to fix spinners, I chop up FG cloth into 1/2 " lengths and mix it with enough epoxy to wet out the FG but not be too resin rich becuz resin alone is not as strong
