I picked up a set of slightly used headers, used enough though that the painted finish burned off and they ae now rusted, not rusty but have a rusted finish. I intend to use them on a junkyard build and was wondering if anyone had any luck recoating them. I considered having them blasted and ceramic coated but that negates their advantage of being cheap. I considered using VHT since I have had reasonable luck with that on manifolds. What have you had success with?

Thanks in advance, Kevin
