Repairing the edges of a deep scratch which have risen UP
I got a pretty deep scratch the other day riding over a rock. I've repaired scratches with ptex before, but this one is different. Along the edges of the gouge, the base is actually bumped UP, rough and abraded. Base-work (i.e. leveling/scraping) is the one thing I swore I'd never do myself, but this seems pretty localized since it is limited to the edges of the scratch. My thought was to very lightly touch up those abraded areas with light sandpaper... or maybe I could even take care of it with a metal scraper. After that, normal ptex for the gouge itself.
Any other ideas? Anybody ever seen this before?
