    Re: Tacoma Exhaust Stain Problem

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

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.
    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.

    Re: Tacoma Exhaust Stain Problem

    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.

    Re: Tacoma Exhaust Stain Problem

    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.
