I've painted a few cars over the last 15 years, starting with my first in high school. I have no training in it, and learned by trying, with mixed results. The first mistake I made in high school was using sealer instead of a high build sandable primer. Any body work I did showed up, even the sanding scratches where I stripped certain areas. Also, buy a long sanding block, and hand block the whole car after primer, it will show any body work or dents your eyes miss. The most important part is to take your time with prep, your paint job will only be as good as the work under it. I wouldn't use the rustoleum, it won't hold up the best, and will be a gooey mess to sand off if you want to re do it. The most important thing is to try it, learn from it, and improve on the next try or the next project! I first painted this car in 1999 with mixed results, and just repainted it in my barn this summer.
