Yes, I've had mixed results w/hi temp paints on exhaust stuff over the years too. I thought white looked so cool, but NOT FOR LONG! This Duster wont be driven much and the Ebody manifolds are easy to get at for some occasional touching up. I'm sure the VHT is way more expensive than the Barbecue paint, so I'll keep that in mind, and also will look at the RUSTOLEUM STUFF cause I know the cast iron likes to turn orange!
