Muffler paint ...

[Kevin Hall]

If anyone needs to repaint the muffler on their MM ... My local John Deere dealer just got in a full case (12 aeresol cans) of JD Muffler Black High Temperature paint. I had them order a case (minimum order) ... I bought 3 cans - 9 are left. JD muffler paint is the best that there is!

If anyone needs some ... I can pick it up and bring it to the Mud Run on Saturday.

Just let me know! :)

[Keith Yates]

Kevin can you bring me a can please?

[Steve W]

Bring me one too.

How much?

[duckbone]

I don't have a muffler, but I'll take two cans of paint for my grill.

Header paint from (ceracoat) Jegs is the tops, the JD stuff is the next best thing in a pinch

[Kevin Hall]

I'll tell you right now ... JD paint is not cheap. $14 and change a can. One can will paint the muffler a couple of times.

I'll stop by the JD dealer on Friday to pick it up .... if anyone else needs a can - just let me know by Friday morning. ;)

I have also heard good reports about this:

I've used the VHT with the ceramic base and I highly recommend it.

MM mufflers have paint on them??? I thought they came rusted and with chunks missing?

[duckbone]

The paint for MM's is the level 352 kit for another $400. :booty:
So Kevin 30 bones for two cans.

[Kevin Hall]

Pat ... roughly, yes. I'll bring the receipt, if anyone wants to see it. ;)

Curiously, have any of you tried that spray zinc PRIOR to a final coat? I don't know how hot a MM muffler gets, but that combo really works on a Det 671 generator stack in a salt environment. Try treating the rust, (ospho- as per directions), then zinc, then paint.... It only held up on my CAT 3516's stacks for about 3-6 months, but the 671's are still lookin' immaculate (10months).

Mako, I never had to. My 692 was twin turbo'd with wet exhausts . You know a sporty engine with blankets but keeping paint on the risers was always problem.

True, keepin paint on those risers is difficult, but I'd bet this would be an improvement. I figured it might help the guys with those exposed mufflers. The zinc really helps keep the rust in check. BTW how often must you repaint your MM mufflers?

Off note briefly, stainless stacks are the way to go and I never fully understood why most companies refused spending the little extra $ on something like that when they're already shelling out $6-10 million (or more!)on a tug/workboat. Alternatively, the zinc first process seems to hold up a heck of alot better externally on those smaller engines. Nothing tames those big 4000hp mains' rust probs in that area. Guess those things generate way too much heat for anything to last.

If anyone attempts the zinc first, I'd be curious to hear how it held up for ya. The key is to clean it good initially, but don't use this method on your grill Duckbone!:icon_chee

[duckbone]

They can't keep paint on those mufflers. I don't care what they use. It would be EXACTLY like trying to keep paint on your lawn mower engine muffler, but it should stick to my smoker and I've been eyeballing it for a sandblast job. Just perfect timing on Kevins part.

Capt - you mean zinc-chromate?

[Captmako]

Capt - you mean zinc-chromate?

It is manufactured by CRC and is called "Zinc-it". It's a cold galvanization product, that when applied acts as a very good primer that prohibits rusting extremely well. Two or three coats applied to a "clean" muffler (get the rust off FIRST) then finish the project with your JD or bar b cue paint (whatever you guys use). It has a heat rating on it, but I'm not sure how high. I just hope those little mufflers aren't too hot when running balls out.... The BSO uses thermal imaging to "see" inbound/outbound vessel traffic here at nite, and I've been told the stacks on our tugs glow like nothing else they see, so they get friggin hot! (they can detect a cigarette butt being thrown overboard from at least 1nm away).

I truly believe you will get much better longevity out of your paint jobs, although I can't guarantee it because I've never tried it on a small engine muffler. I'm guessing it will cost app $10/ can. As with any priming/painting, preparation is the most important factor. If you spray it on a hunk o' rust, it likely will not work. If it works, great, if not, you lost maybe $10 or so... If nothing works... Chrome it babeeee!!!:icon_chee Perhaps some of our scientific "bretheren" may know more detail why this will/won't work for this type of application.

[duckbone]

Ceramic coating like they do headers would probably be best. I don't know how well a powder coat job would hold up. Either one would have to be done right not some spray on home job.

They get plenty hot ... glowing red hot. If you've ever taken a look at one of the mufflers after/while running WFO ... in the dark, of course ... you'll see exactly what I mean. ;)

[Kevin Hall]

Guess who completely forgot about the paint today? :eek: :rolleyes: I had it in the truck and completely forgot about it. Oops. ;)

[Steve W]

Save me a can I will probably be back down there in a couple of weeks.

[Kevin Hall]

It's not going anywhere ... ;)

Also a good visual indicator of whether your engine is running "balanced" on each cylinder. If one side is redder than the other or no red at all you got some issues that need looked at immmediately.

[Kevin Hall]

Mine runs red hot all the way across the muffler ...

The JD paint seems to be holding up ... I've got a little "discoloration" in the hottest part of the muffler, but it's not coming off!

Yeah me too.
