If you're talking about the candy red, it's a bit more involved than buying a can of spraypaint.
It's a 3-stage finish which begins (after prep & primer) with a silver basecoat, followed by a clear (candy-apple) red and finished with a clear lacquer, and from experience I can say it isn't a straightforward job.
To illustrate the point, I used to refinish Jap sportsbikes for a living, and on more than a few occasions I'd sand back the original factory finish to uncover up to four previous attempts before the job was considered satisfactory. I'll emphasise the point - these came out of the factory like this.
If you've got the equipment, the paints are available from most auto-refinish suppliers (Google House of Color). It's hugely rewarding to stand back and admire a good paintjob, but it would be a baptism of fire if you haven't done it before!
