Re: Paint not hardening??
If you've got the money to spend and can get your hands on a compressor and paintgun, go to an automobile paint supply shop. $40 bucks or so will get you a quart of paint and hardner which you mix with the paint.
What's really nice about this paint is not only does it harden (just like on a car), it's resistant to gasoline. Nothing worse than giving your bike a sweet paint job only to have it messed up putting gas in the tank.
