My mufflers are in a shockin state ive done some of em in flame proof paint. But there arnt my colours textures avalibe like there are for engine paints. My questions is does anyone know how hot mufflers get and tell me in degrees celciuse/faranhent. Can i use engine paints on mufflers or does it no withstand it. My guess would be flame proff on the first part of the muffler and heatproof on the further outer end.
