This is interesting. I use a product at work called Q-bond that is basically what you are describing but built for repairing. You fill in what you want to repair with the correct powder and then add super glue. Pretty amazing stuff. https://a.co/d/02cN5Wiv

There was a post on Corvettefourm about how to fix it, and it turned out pretty good. I bought the kit, but I misplaced it. https://www.amazon.com/dp/B00HX704NG
