    Yes the best that we can get it in there. Even with the interior out and those vents stripped from the quarter panels, it's very hard to get anything in between the outer skin of the quarter panel and the inner structure. Maybe an 1/8 of an inch of clearance. So treating the metal is the most important part. If u can treat the aluminum and then seam seal it after paint, no water should be able to get back in there.

    Looking to purchase an F12. Did Ferrari end up with a revised mesh and cover the repairs after the 3 year warranty expiring on customer cars? If not, what was the cost of the repair?
    Also, is the consensus the metal mesh rubbing up against the aluminum body the root cause of the paint bubbling?

    I recently took delivery of my manual 991.2 GT3. The car is alive. Best Porsche I have ever had or driven. Get it.

    i dont know if they did but id be surprised if they did. by the time this became noticed and well known it was pretty late into f12 production from how i remember it.

    My understanding is a protector was developed so it is not metal on metal. I have a 2016 F12. No sign of this problem on purchase. Developed 10 months later on one side. Warranty covered it and they corrected both sides. Costly repair if not. About 12 k in warranty dollars, zero to me. The problem is if it’s not done by Ferrari they may not put the protector on? And the problem could recur.

    i bet if u take apart the screens and add some protection to these tabs...like dipping them in a coating or even installing plastic or rubber washers.
    you will help it so no oxidation.

    colonels if u don’t have a issue.
    i would recommend if u are ok with taking apart rear on your own
    or take to ferrari and add those shims on the steel tabs and u will be fine.
    i have to this conclusion from a couple posts here and looking at the image i posted above.
    it’s a easy fix if the car hasn’t started the corrosion.

    so from dealer they say it is covered under 3 year factory warranty there is no extra corrosion warranty that is longer. however my dealer is contacting them to cover it out of warranty because it is such a well known issue. the entire black mesh part is steel. i have not gotten an official answer from Ferrari NA if they will cover it yet, but when i do i will detail as much as possible what is done.
    talking to another person who recently had the fix done he said they repainted both 1/4 panels and roof and they also sprayed up under the wheel well where the steel mesh part contacts the aluminum body panel. he was unaware of any plastic spacers or barriers placed. i believe Ferrari thinks that those areas were not properly treated with paint in the manufacture of the car originally which has lead to the galvanic corrosion and that a thorough respray of the underside will correct the problem.

    from a website i believe this is what is occurring with a very thin layer of paint/treatment on the underside of aluminum from the factory and the black mesh all steel part with black paint. Ferrari is choosing steps 4 and 6 as solution:

    Galvanic corrosion occurs when two materials (an anode (aluminum) and a cathode (steel)) come into contact with each other and an electrolyte. Electrolytes can be environmental factors such as humidity or rainwater. When these factors come into play, electron transfer will begin to occur. Depending on the level of resistance in an electrolyte, this transfer can happen much faster.

    There are a few steps you can take if you MUST use these materials together.

    1. Add an insulator between the two materials so they no longer connect. Without that connection, the transfer of electrons cannot occur. Well Nuts are a commonly used fastener to help separate materials that can suffer from galvanic corrosion.
    2. Use materials with the same potential. Metals with the same corrosion resistance are typically ok to use together.
    3. If you are in a situation where only one of the materials will come into contact with an electrolyte then transfer of electrons will not occur.
    4. If there is a coating on the cathode it can prevent the transfer through increased resistance.
    5. Consider your environment before installing. Choose materials that will work for your environment.
    6. Coat or paint your assembly (completely) so that the electrolyte cannot make contact with the materials
    7. Use neoprene EPDM or bonding washers as a barrier in between the metals.

    Its a bit involved to pull apart otherwise a simple fix as you point out.
