I don't think its a bad idea. If you do what I said with the auto body paint, Take your time and do a good job, It will look so nice your friend won't believe you painted it
Use a scotch-Britte pad or a S.o.S. pad to scuff all the parts to a dull finish so the paint/primer will stick to it, Then wash all the parts really good. Follow the directions on the can. Most good auto-body spray paint cans will spray in a line not in a crappy circle giving you more control while painting and a better finish.
When its all done and dry you can polish it to a high shine using car wax/polish like turtle wax.
