I masked off the area where I sanded through on the last work session. I used a rag with MEK to clean the fabric in that area down to a bare surface. I can see why the polyfiber products are so successful- this whole process was much easier than I expected.
The damaged area needs at least one inch of overlap, so I made the patch to those standards.
Since the patched side of the elevator isn’t going to be ready for spraying, I sprayed all of the other surfaces with their second coat of polyspray.
