Turbo 383 in a A-body Barracuda
I used vht on my bug and it lasted awhile but it went from flat black to light grey to a brownish color. I have read that it works alot better when wrapped, up to 2000 degrees with 0r 1200 without but I dont know if they mean under the wrap or paint it on the wrap I have painted my wrap with it and that does work pretty well, Just gets kinda krusty.
