painting headers?

[tellyv]

I have a customers car he has a set of hooker headers there black and look like crap there in nice shape but are peeling I have never had good luck painting headers Ive tried specialty paints even por 15 heat paint and never had good luck, He's a great customer and has spent a but load of money so Instead of buying another ceramic coated set I thought I'd see if anybody has any good ideas. thanks telly
