This is a truly beautiful thing! I love rust.
If only you could find some genius to fabricate metal bumper skins so you didn't need to fake them, epic job.
i love it when someone thinks so far out of the box that there's no return, sooo many standard A4's it's good to see this.
Sorry for being a bit thick but.... thats actually a paint finish? Pretty amazing if it is! Kinda like the Rat Rod look.....
I patina'd my 56' bus and rubbed through to an off white under layer from the dove blue top coat, I reckon once fully painted you should gently rub down on all the top curve edges to give it that natural worn look....just like being in Cali for 50 years you know like Arnold Schwarzenegger
