Another Sticky Dash Issue

nis350

I have similar experience.

Z is always in the garage and rarely driven, and the dash became a bit sticky last year. However, the garage does get up to 100+ during Summer in Socal here.

however, the g37s is DD (outside) and the dash is just fine without any stickiness or discoloring.

after a good cleaning with water, the stickiness is gone on the Z's dash, but it turned a bit grayish after awhile. I've treated it with meguiar's natural shine vinyl protectant and it's back to the normal color for now. Guess I have wait a bit to see if the stickiness/shininess comes back.
