This is amazing man! I've been doing body work on cars for around 12 years now, and as far as paint goes, I would recommend powder coating it. Some paints are tough but not as tough as powder coating. I'm not sure if you would weather it or not, or if you can even weather that stuff like paint, but that's what I would do. To me, seems the best way to keep it looking good for as long as possible haha. Keep up the good work man! I love checking in to see what you keep accomplishing!!!!!!!
