Header Paint and hearder heat wrap ?'s

i have header wrap on my headers in my v8 vega and no problems.... been on it for 4 years and i had to re wrap the one pipe.. (it goes out fender well and back under so tired rubs when turned all the way) and still looked good shape... normal surface rust as if you had stock headers.... made the engine bay and inside the car alot lower temp. i also dont drive it in the rain for moisture problem
