Painting the exhaust black

The body shop got some overspray on the muffer under the drivers seat and some on the exhaust. BJ8. I've scuffed the surface with a 3M scuff pad but the paint is still on. I've scuffed the entire muffer system, for I want to paint it again. PO painted it black, and it was fine. But now that it's been in the body shop for so long, bits of it have been bead blasted and have over spray on it.

I've read that BBQ paint is OK to use. I bought 2 cans of Rustoleum black BBQ spray paint. Will it be OK to use over the overspray?

I've heard that even BBQ paint will flake off down the road, maybe 100 miles later?

What should I do, what should I use, to paint my muffer system black.

Thank you, Roger
 
The exhaust was originally painted black. The BBQ paint may work ok. I have had very good luck with "Stove Bright" #6309 Met. Black paint. Distributed by Forrest Paint Co., Eugene, Oregon. (541-342-1821) You can probably find it at a stove shop. It has stayed on the very hot parts of my headers for several years.

Dave, did you prepare the metal first? If so, what did you do, use.

Did you use a primer?

As I mentioned, the PO painted my complete system black and it seems to be holding up fine. I would guess PO painted it about 1,000 miles ago. I need to repaint certain areas because of bead blasting and over spray. Thought it would be best to paint the entire system for consistancy in color.
Thank you, Roger
 
I have used BBQ paint on manifolds and exhaust pipes over the years. Do not prime for it but remove all loose paint, rust, etch. Do all the usual prep work, specifically, read the can it's in.

If the overspray is on a front resonator or rear muffler it won't have near the problems that you're worried about. Flaking and burning off is much more a problem on the exhaust manifold and sometimes the downpipe. Once the exhaust has "turned" and is running along the underbody of the car it's less likely to cause heat damage to BBQ paint.

Some will reply recommending high-temp engine paint, I hate the stuff. High-temp engine paint has almost no solids and even less binder. You spray the stuff on and it looks good for a week before it starts flaking... and don't every spray it with water when hot. BBQ paint has much higher solids content and sticks much better.
 
Thank you Dave, Doug.
I sanded the overspray off, and scuffed the entire system. I air hosed the dust off, then finished with a grease and oil removing solvent with a rag. Painted all. Took one and a half cans. Looks fine. Time will tell if it holds.

Firm believer in spending the time up front and doing it right, the first time. Thank you for the guidence. Roger
