how was your prep on the stand? paint doesn't like to adhere to bare metal, some sort of metal etch or primer first will help. as far as baking, i would assume everything is welded and nothing removable? a heat lamp or even one of those afterburner type space heaters probly wouldn't get you anywhere near the temp you would need. best suggestion would be to properly prep before painting or pay for a ceramic powdercoating or something.
