 Topic: keeping paint on muffler
Posted: 10 Dec 2010 at 7:07am |

How do you guys keep paint on mufflers? I "m using black paint that they use on headers, but it seems to flake off. The muffler is on a wd- 45. Thank you.

How are you prepping the muffler? It has the be free from oil, and scuffing it lightly with emerey cloth will almost guarantee adhesion.

Flaking off usually points to the paint not bonding to the surface,at least that's my observations.
I've used VHT brand of paint, but used their primer first, then the color coat. I sanded it down real good,cleaned with laquer thinner, primered,painted.
VHT says you don't need their primer but...it does fill in the sand marks well,
Did this on a nice warm day last summer....so far ,so good.

I found with Hi-Temp paint, once the manifold is clean, I set it on top of the wood stove, get it warm, blast it with paint, then set it right back on the wood stove and bake it on. I usually hit it with 2-3 coats

It was on the local news a couple days ago that a garage blew up. It seems that a guy was painting a car, and the garage was being heated with a wood burning stove.
He received 2nd and 3rd degree burns.

For a work tractor? no paint stays on red hot muffler. For play machines we use BBQ grill paint from any hardware it works as well as any I have tried. Stays on except for red hot. Not a pretty black but looks better than rust.

I used the same stuff Butch mentioned (BBQ paint) but first I removed the paint that came on the muffler when I bought it. I plowed with it this fall for 50+ hours and it still looks like new.

BBQ paint is also available in a couple shades of gray at some places. If you really need it painted to stay painted you'll need to send it out and have it ceramic coated, but I wouldn't spend the money.

I use the rustoleum BBQ flat black on my pulling tractor pipe. It pegs the 1500 egt gauge, and the paint still looks great. I didn't even prep it very well, figuring it wouldn't last too long. It proved me wrong!

I have found on motorcycle and tractor mufflers that what DonDittmar says about getting it warm, painting, and baking it on works. I use an old electric oven. Also I found out, never mix brands of paint, they won't work with each other.

I put black bar-b-que grille paint on my pick-up exhaust manifolds about 25 years ago, and it held up, Darrel

I used bbq grill paint on the 7080 and 7060 pipes. I lightly sanded to get some of the loose rust off of them wiped them down with "prep-sol" and painted them. Pulling a ripper, disc, or whatever is behind them they are working. I have not had a bit of problem with the paint comming off at all.
