Hey everyone, I am doing a restomod with my 12 yo son on a '65 Coupe! The body is in decent condition but definitely will require some work. This car will be driven by my son when he turns 16 so I want it to be done right! This picture shows the worst damage that I see so far, I haven't stripped the paint off yet to see how much bondo is underneath.
What should I do hear? Grind it out and fill with? What's the best course of action here?
