No big deal but I have a squeaky rattle from the plastic air vents on top of the dash.  Silicone or furniture polish sprayed into the join cures it for a few months but it returns.  As said no big deal, just wondered if anyone had a longer lasting fix?

There was/is a product Carl Gummi Pleg ( or something like that) which I used on a previous car with squeaky dash. One application cured it. Also excellent for rubber door seals.

Thanks for that, a google found the name Carl Gummi Pflege, you were so close.. I'll give it a go, It will be handy in winter time too, stop the frozen door seals.

I am pretty sure all my cars start to squeak when it gets as hot as this, worst one was an Avenger the nylon steering bushes used to shriek

until I either sprayed them or the weather changed.
