Found a filler/rust hell from my car. I already painted the orange sides, but found other cracked panels with way too much filler, so might as well just repaint the whole car. It will be a DIY job with every crack being sanded to metal and treated with phosphoric acid, but this time I'm going to leave that filler in, just because I don't have a place to sand the whole car down to metal. Let's hope that next time it starts to crack I will have proper resources to do real bodywork.
Here are some photo edits of how I'm goin to paint the car.
And here's an emblem test made with my new 3D Printer. It's PETG so should handle heat well. I'll see how it looks after some sanding and fresh paint.
