    Re: Correcting very soft plastic back panel (Mustang)

    Yep, had real trouble with this rear decklid panel, it`s not a typical coating and can easily fracture with a light finishing polish. Black B&S pad on the GG6 speed 3.5 with Griot`s Perfecting Cream did us in and we were left with micro fractures all over the place. I believe someone else on the forum documented that he was able to sand off this top coat and get it acceptable, my neighbor and I stopped once we saw the fractures and didn`t investigate further correction.

    I have a similar area in the dash above the glove compartment of my Macan.
    What about hand polishing the Mustang rear fascia?

    Re: Correcting very soft plastic back panel (Mustang)

    Welp, I got it done, and will post pictures soon. I used a Griots 3" orange pad with Menzerna 2500 and it worked great, but was a bit harrowing. As I was carefully polishing on speed 4, I could smell the foul odor of melting plastic. I was applying almost NO pressure. I can see how this decklid could easily get mucked up. I followed with a black CCS pad and 3800, which made a tiny difference, but really the 2500/orange got the job done. These two pads went into the trash afterwards. Sealed it with Collinite Detergent-Proof Super Double Coat Permanent Clear Coat Safe Auto Wax.

    This was odd in that it did not respond to hand polishing at all, and in fact hand polishing would mar it. I think the DA melted off a layer, which luckily resulted in shine.

    WaxAddict- Glad you got that sorted out, sounded like a big PIA.

    Why`d you go with the 476S?

    Re: Correcting very soft plastic back panel (Mustang)

    Not the best two photos, but hopefully you can tell it`s defect-free and undamaged (I hope).



    Accum: I used 476 because it was closest to me, thus requiring the least effort. Not to sound snarky, 476 is probably a "decent" choice, but best for this would be a coating or many layers of Klasse. This area needs some "real" barrier between itself and the hands and fingers shutting the trunk, and the inevitable waterless wash (microfiber towels).

    WaxAddict- OK, I see you did at least consider my "why not use.." choices

    This has been an eye-opener for me, never woulda thunk that panel would be stupid-soft *and* that easily trashed...I`d go nuts (until it was PPFed).
