Thanks Erik
I just used some rustoleum enamel spray paint, and including the white base paint I probably spent a total of $15 dollars on all the cans I needed. I had never taped anything off like this before, but it only took me about two days to tape it all off and paint. It probably wasn't the best way, but I tried to get the tape as close to where I wanted it as possible, then I took my exacto and very lightly scored any excess that needed to be took off, then peeled it. It worked pretty good for me, and it didn't cut the paint under the tape.
The weathering was really fun. I just scuffed it all up a bit with some steel wool, then took some 400 grit and folded it and used that to make the bigger scratches. Then just watered down some black acrylic, brushed it on and wiped off. Took me about 2 hours.
