Put a piece of tape on it for temporary. They sell really good colored duct tape, and there is a new breed of Mylar tape (expensive) that is tough as nails.
Ceconite spot repairs are trivial, but I always glue a piece of pinked edge fabric over the boo-boo, then refinish with clear/silver/white/color. Ed has been successful at removing old finish and matching the edges - I have never been able to do that.
If fabric is damaged, or silver layer is gone, then concur with Bob. Strip to bare fabric with lacquer thinner about an inch past the damage, glue on a patch with super seam, then apply nitrate/silver/white/color dope. On small repairs you can skip the clear layer and do buildup with silver.
If only the color coat has flaked off and the silver is still there, then scrape off any loose flakes, sand smooth, and spray with silver/white/color.
Either way, tape the area for silver, then remove tape, wet sand raised edges with 400 grit, and blend the white and color by feathering the spray into the surrounding area. Dope is really easy to blend because it melts into the coat below.
For a small repair in an inconspicuous area, you can brush on dope and it will be a perfectly serviceable repair, but it will look like crap.
Most important thing is never apply dope during high humidity. Blushing happens quickly and degrades the integrity of the repair.
Get the process manual and follow it. Ignore all outside advice that contradicts the process manual. Again, dope is VERY EASY to repair as long as you RTFI.
