I used what I use on the ears of Model horses… it’s called Super soda.
If you take Zap a Gap glue… or some other brand of Super glue… and place some on the chip… then sprinkle baking soda over it… it forms a rock hard and almost instantly dry RESIN…
You have to do it in layers… building the ship up to the level you want… but it worked on my Brown mother’s missing scale… 😀
It’s also sandable… and carvable too… just like a resin. 😀
It can get messy… so I’d practice on some… toy or somthing first… but I’ve foudn it works wonders for fulling gaps… etc. 😀
2 part Sculpting Epoxy works too. 😀
