High Temp Clear Coat?

[honda250r]

I made a new pipe for my motor scooter i used a stock cr80 pipe and cut welded and bent it to fit. I like the looks of the bare metal pipes with the blueing from heat and was wondering if they made high temp clearcoat that i could paint the pipe with so it doesnt rust. Anyone know if there is high temp clearcoat or something else i could use to keep it from rusting
