As the title really. I seem to have a few pieces of squeaky plastic, with the worst one being the joint between the two parts of the parcel shelf support........driving me nuts.

Any thoughts ? 2011 Stornaway Grey 5.0SC Autobiography

Buy some silicon spay and give it a blast.

So silicon worked well on some of the squeaks, but found the worst one is actually the leather on the rear seat rubbing against the plastic.......any ideas ? 2011 Stornaway Grey 5.0SC Autobiography

Candle wax on the plastic where it makes contact with the leather

Will give that a try.... Does it last or need re-doing regularly ? 2011 Stornaway Grey 5.0SC Autobiography

Just rub a candle on the plastic, I did this last year on a squeaky part in my car, not needed to do it again since.
