I hope I am not alone when it comes to saving a broken damaged item form the garbage can. I spend way too much time than makes sense, but there is that feeling of satisfaction of making it better, and there is absolutely no pressure of working on rare or mint items.
So when I bought this car, it was what was left of a Dynamic Mirage. The body was cut so high no motor would fit under it. It also had a really bad arch trim and sides that looked like the Bonnie and Clyde car.
But with all that,the factory blue/back and the shape of the Mirage body said to me, this is worth a go.
My technique is to lay clear tape on the outside of the problem area then trowel epoxy on the tape from the inside.Then it can be sanded polished and painted. You have to work with gravity, so I only do one corner or side at a time. Wish me luck, 
or tell me I am crazy.
