Tacoma Exhaust Stain Problem

[tguil]

This has been an ongoing problem on all three of my wife's white Gen 2 Tacomas (2005, 2011 and 2015). We live on a gravel road and every winter we end up with a gritty stain on the fender above the exhaust pipe. I think that it is a mixture of exhaust condensation and dust. After ten years you would think that Toyota would have a fix for this. They don't.

Clay, solvents and polish do NOT remove the stain. It's almost like another layer of paint. . The only thing that has worked for me is to buff off the stain using Meguiar's Ultimate Compound applied with a three inch pad on a PC. Then I then apply a coat of Meguiar's Ultimate Wax. I do this a couple of times during the winter months. Anyone have a better idea? I don't want mess with changing the exhaust.

Clear bra, maybe?

[tguil]

Thought some about trying that. I'm a little concerned that heat might be a problem with the adhesive getting messed up. How hard are the bras to remove?

The truck is garaged every night and I'm thinking about keeping a bucket of ONR mix ready to use on the fender after every winter drive.

•But...Sometimes you gotta do what you gotta do.

•And...Since there's only so much paint
back there that you can safely remove...

I had to use compound numerous times on both the 2005 and 2012 Tacomas. Because the stain is only on the surface of the paint, I was able to stop using the compound before I hit the surface of the finish. No paint damage. The stain is almost like a "ceramic" coating on the surface. Dust mixed with warm moist exhaust. In the winter there is considerable moisture in the exhaust at start up and when it's really cold, the moist exhaust "pours out" for a considerable amount to time while driving. I do not have this problem in warm weather.

Toyota is aware of this problem but has not come up with a solution. The folks in my dealer's service department suggest waxing the area a lot. An AIO wax won't begin to clean up the stain.

About a down-turned exhaust tip. I haven't had one of those on a vehicle since 1960. Cool then but not so cool now. I will however check to see what a muffler shop can come up with.

You may look into having the turndown placed just after the exhaust crosses over the rear axle like some off-road vehicles do. That would avoid the looks of a turndown.

Also, seeing if you can get a sample of a paint coating, like cquartz, may help. They're reported to be very easy to clean and keeping things from sticking. I'd probably try that before the turndown idea.

Now you have me wanting to check my Tacoma more closely.

Thanks for the suggestions. Any problems with exhaust fumes from having the turn down under the bed of the truck.

If you don't drive on dusty roads you may not have this problem.

The new models come with a little patch of clear bra over that area. I thought that was interesting.

Here we go an old post that I made five years ago. I purchased a fourth white Tacoma in 2018. My wife still has her 2015 Tacoma. In the five years since my 2016 post, I still have not found a solution to this problem other than Ultimate Compound followed by an application of wax. Does anyone have a suggestion that might work for removal of this stain. By the way, my wife's Tacoma is almost six years old. I have used the compound on it once or twice every year and have not cut through to primer...yet.

there are PPFs that have a higher heat tolerance. Ceramic coating would help as well. I frequently ceramic coat exhaust tips and I noticed that they are so much easier to clean afterwards.

Just curious - have you tried different LSP's in that area? Seems like if one has proven to not resist staining I'd want to rotate through some different options. Instead of wax try an Acrylic sealant/sio2/tio2 etc.

[tguil]

I agree with comments above. Maybe I should try a better sealant/coating...something that I can buff out without taking the chance on damaging paint. I also have considered cutting off the exhaust pipe under the truck bed and installing a decent looking turn down exhaust extension. Two reasons for not doing this...is it really safe and what happens with all of the moisture exiting the exhaust. This is mostly a problem in cold weather. I'd really like to find a chemical that would remove the stain without damaging the paint....and easy on, easy off chemical. I drive on eight miles of gravel road daily. The dust and exhaust moisture and heat cause the problem.


It's almost time for my wife to trade her truck. This little problem may just be a deal breaker. Four trucks with this problem is enough.
