Does anyone know of a good exhaust coating that actually stays on

[crazypete]

None of the dupli color ceramic coatings seem to stick to the h pipe longer than maybe 2-3 warmup cycles. I'm running an aftermarket pipe with 2 high flow cats opposite the muffler inlet flange. I keep painting them with the off the shelf 1500 degree ceramic engine paints to keep them nice and fresh but the paint seems to disappear after 3-4 warmup cycles. Has anyone found anything that actually sticks to the metal? It's not the dynamic wind and debris that strips it off since I painted my headers with the 1500 ceramic paint and it flaked off mostly by the second warmup cycle.
