what kind of paint should I use on my stock ? iv sanded all the rust off . just wanna help preserve it from the salt water.

WD40

iv already removed all the rust . im looking for suggestions what paint to use.

Let me see if I can find the stuff I used in my basement. I haven't had any issues with it coming off I probably have 50 hours on it.

id appreciate it !

nothing will stay on!!

Been a while since I did a stock one but the last one I did I went and got the High Temp black spray paint that u would use like on a woodstove..Held up really well

something has to work we have boilers that get way hotter then an exhaust does and the paint stays on them lol

I tried high temp header paint and it burnt off in an hour or so

i never seen any paint stick on ex

if the metal is not cleaned properly when painting the exhaust. the paint prolly will not stick. my exhaust was not rusted that bad just wanted to do preventive maintenance.

I know what u r sayin about cleaning it before u paint. Just letting u know it's a waste of time

My theory is........Your boilers are made of heavier material that don't experience the number of expansion and contraction cycles the thin gauge pipes do. The paint gets dry and brittle, and does not move with the metal.

true !!! damn ill just paint it black and touch it up from time to time

Go ahead and paint smart boy!That fuker gets cherry red hot and there is Not a fuking thing that will stay on it!!But you go ahead and have at it

Just paint it with cheap black spray paint and touch it up

I had 1200 deg stuff stay on for 2-3 trips. Then gone. WD works pretty good smells good when it burns of to.

I used rust-oleum heat proof paint on my huge ass bbq pit(5yrs)gets between 500 and 600*F and on my atv muffler(2yrs). had no problems of burning or peeling. but I also put about three coats.

My exhaust doesn't glow red hot. My marsh mellow exhaust will just have to be painted from time to time . I got some stuff from work I'm gunna try they put on the heat exchanger tubes at work. It's kind if like flex seal. Jimmy w no need to be an ass

Fresh water rinse after using it to get the mud off (if any).
Idle it up to dry off the water.
While running at ~2000-2500 RPM's, spray WD-40 very liberally through the brush guard above/in front of your flywheel depending on if you have vertical/horizontal shaft engine.
Let the muffler cool down and then soak it down good with WD-40.

You will not get any paint to stay on the muffler and especially not the headers. The only coating that will stand up to the heat would be a ceramic coating...but that won't stay adhered due to temperature cycling....thermal contraction/expansion.

We use ceramic coatings on process heater tube exteriors which see direct flame firing in a firebox over 1400 degrees F. The tube metal temperatures see 900-1000 degrees. The main reason we use the ceramic coating on the tubes is to prevent scale from being created on the tube exteriors. The scale decreases the heat transfer efficiency over time....meaning you have to fire your heater harder to maintain the same process outlet temperatures. At any rate, the heaters will stay in service anywhere from 5 to 8 years before they are cycled down to ambient. Thus, we don't have an issue with the ceramic flaking/chipping due to thermal cycling.

Black high temp paint. Touch up every 20+hrs

We use the stuff at work to prevent the brine ( salt ) water from corroding our tubes. I understand what ur saying I'll have to try w-d 40

Fresh water, then WD40 then fresh water again. Paint will do nothing to help. The water will rinse off most of the salt, the WD40 will pull off what is left. When you rinse it a final time you will notice and shine to the motor. The salt will be gone and you will be good to go. Your motor will not have that nasty oil build up or rust.

cerakote.

The one I am running now has been cerokoted and that shit is suppose to be Tuff as Woodpecker lips and it is coming off

Under a load running WOT it does have spots that get cherry red on most!

Jimmy still gives u no reason to be a total ass. And no that's no what's we use on our exchanger or boiler tubes , we use that on our heater in our star age tanks that only get 85 degrees. I didn't know u were the know it all of mud motors. Who gives a shit how long uv ben messing with mud motors. Does not make u an expert. A shitty mechanic can say the same thing if he's worked on motors 30 years ? This is a forum and what it's intended for, to share information. I Never even argued that the paint won't come off. I'm looking for something that would hold up the longest that I just need to touch up time to time. But I'm ok with just washing it down and cleaning it with W-D 40, them rinsing it off. Look at the topic title. Don't get ur panties in a wad just because you disagree with someone.

If its a stock exhaust it will rust from the inside out ....If it's a marsh mellow it's stainless and if you keep it cleaned and oiled, it will discolor but not have any surface rust. Jimmy ain't being an ass, he's jimmy...... and he is correct.... nothing will stick to that thin gage metal when it gets hot and expands..... it will flake off after an hour or two of running hard.....

Oh and with a stocker on a horizontal motor, what rusts and comes apart on the inside will fall down through the header into the heads and do all kind of damage..... my buddies did that after about 8 months and he ended up with a new motor from Briggs warranty......

There's no rust on the inside. Just on the outside. Cleaned the the exhaust easy but the metal bands are a bitch to clean. Like I said I'm looking for a way to preserve the exhaust not necessarily paint it. If the WD-40 works I'll do that. The exhaust wast bad just wanted to clean it know then later.

Keep it clean...it will rust....do you run salt or brackish water?

Salt , brackish, and fresh. I'm afraid to try to unbolt the exhaust and clean the inside. My top bolts on the exhaust are realy rusted, afraid they will snap. Thanx I might try corrosion x. Alls I have is WD-40 right know. The bands are the only corrosion I have left on the exhaust. But it's no big deal. Just wanna keep my motor in nice working and clean condition .
