Sticky Lexus Dash

[pvs2487]

I've got a 2009 Lexus ES350 with 170,000 miles, which has been a very solid car.
There are several sticky spots on the horizontal portion of the dashboards, worse of course vin the hot weather.
I understand that this is a recognized issue, and some dashboards were replaced under warranty; I'm well past that window.
Is there any sort of sealer I can use to cover these spots? There are dash covers available (I have one on my 1970 MGB), but I'm not sure that I want to go there just yet.

Any suggestions welcome.
Thanks,
Peter

Have you contacted the dealer about this?
I know your car is old, but Lexus has been know to address this issue well outside of the warranty.
