No doubt there are many posts on all aspects of fabric work, however I am trying to understand the best process for my repair scenario... I need to cut a small hole (1" dia) in my ailerons to access and tighten some attachment hardware. the fabric is Superflite and the top coat is Sherwin-Williams Acry-Glo urethane. My questions are: 1) how much larger than my anticipated cut should I remove the coatings and take down to the fabric? 2) can I use a chemical paint stripper to remove the top coat as well as the base coats? 3) what is the best technique to feather the patch into the old finish? Any help will be much appreciated!
