Tell us about yourself!
I painted my bike recently and I used rustoleum and it came off kind of easily due to the colors I used and my sanding, so my suggestion is to sand very well, use a rustoleum primer meant for outdoor use, sand very well between coats, use a minimal amount of colors, use lots of high quality enamel (google it), and wait at least three weeks after painting it before you start using it. All the materials he used are in the actual instructable. Good luck, and as a last note, know that this is a big project and you should be aware of that.
