The 2.4L Ecotec manifold in my Slingshot began rusting and I painted it with VHT stuff that claimed
1200-2000F and it burned off immediately. It did leave some sort of brown coat that
has not rusted yet. Am thinking of putting additional coats on, but wondered if
anyone knows of a better DIY product that might not burn off?

It is not rust it is patina. What about the inside of the manifold that sees all the exhaust gasses?

Did you follow the directions on the can / on the website? There's a way to cure the manifold off the car in your kitchen oven and there's a different method to cure the paint if the part is left on the car. "Prep is everything" when it comes to paint. A bad painter can mess up a car royally with top-of-the-line Glasurit and a good painter can get good results with cheap Limco.

Only, I suspect, if you are single, or want to be.

Followed it to the letter but the final stage called for driving it 30 min
and during that time, when slowing for turn, there was an acrid smell of
the paint burning off. The smell didn't last too long, and as I mentioned
earlier, it did leave some sort of coating that has held for the last 1500
miles although it looks to be wearing off. The red paint did hold up on the
manifold where it bolts to the engine and looks weird with only that portion
having a color...the rest being brownish. I might wait till winter when I
won't be driving the Slingshot much and pull the manifold off and have it
Cermacoated. There is a shop in Charlotte that does that kind of work.
